Nearly 80% of the world’s population lives in low- and middle-income countries (LMICs) and these regions bear the greatest burden of maternal, neonatal, and child mortality, with most of the deaths occurring at home. Much of global maternal and child mortality is attributable to easily preventable and treatable conditions. However, the challenge lies in reaching the most vulnerable communities, especially the rural populations, making it imperative that maternal, newborn, and child health (MNCH) interventions focus on communities in tandem with facility-based strategies. There is widespread consensus that delivering effective primary health care (PHC) interventions through the continuum of care, starting from pregnancy to delivery and then to the newborn, infant, and the young child, is an integral component of health strategies in high-, middle- and low-income settings.
Despite gaps in research, several effective community-based PHC approaches have been proven to impact MNCH positively. Implementation of these strategies is needed at scale in LMICs and in partnership with all stakeholders including the public and private sector. Community-based PHC, operating on the principles of community engagement and community mobilization, is now more critical than ever. Further robust studies are needed to evaluate certain strategies of community-based PHC and their impact on maternal and child health outcomes, such as the use of mobile technology and social franchises. Recognition of community health workers (CHWs) as a formal cadre and the integration of community-based health services within PHC are vital in strengthening efforts to impact maternal, neonatal, and child health outcomes positively. However, despite the importance of community-based PHC for MNCH in LMICs, the existence of a strong health system and skilled workforce is central to achieving positive health outcomes in these regions.

For decades, researchers have been puzzled by the finding that despite low socioeconomic status, fewer social mobility opportunities, and access barriers to health care, some migrant groups appear to experience lower mortality than the majority population of the respective host country (and possibly also of the country of origin). This phenomenon has been acknowledged as a paradox, and in turn, researchers attempted to explain this paradox through theoretical interpretations, innovative research designs, and methodological speculations.
Specific focus on the salmon effect/bias and the convergence theory may help characterize the past and current tendencies in migrant health research to explain the paradox of healthy migrants: the first examines whether the paradox reveals a real effect or is a reflection of methodological error, and the second suggests that even if migrants indeed have a mortality advantage, it may soon disappear due to acculturation. These discussions should encompass mental health in addition to physical health.
It is impossible to forecast the future trajectories of migration patterns and equally impossible to always accurately predict the physical and mental health outcomes migrants/refugees who cannot return to the country of origin in times of war, political conflict, and severe climate change. However, following individuals on their path to becoming acculturated to new societies will not only enrich our understanding of the relationship between migration and health but also contribute to the acculturation process by generating advocacy for inclusive health care.

Migration is a reality of today’s world, with over one billion migrants worldwide. While many choose to move voluntarily, others are forced to migrate due to economic reasons or to flee war, conflict, or persecution. Such migrants often find themselves in precarious and marginalized situations—particularly asylum seekers, refugees, and undocumented or irregular migrants. While often viewed as a single group, the legal status and entitlements of these three groups are different. This has implications for their ability to access health care; in addition, rights and entitlements vary across the 28 countries of the European Union and across different parts of national health systems. The lack of entitlement to receive care, including primary and secondary care, is a significant barrier for many asylum seekers and refugees and an even greater barrier for undocumented migrants. Other barriers include different health profiles and awareness of chronic disease risk amongst migrants; awareness of the organization of health systems in host countries; and language and communication. The use of professional interpreters can help to overcome communication barriers, but entitlement to free interpreting services is highly variable. Host countries need to consider how to ensure their health systems are “migrant-friendly”: solutions include provision of professional interpreters; ensuring that health care staff are aware of migrants’ rights to access health care; and increasing knowledge of migrants in relation to the organization of the health care system in their host country and how to access care, for example through the use of patient navigators. However, perhaps one of the greatest facilitators for migrants will be a more favorable political situation, which stops demonizing people who are forced to migrate due to situations out of their control.

The construction of the concepts of diplomacy and health diplomacy must consider their conceptions and practices, at both the global and regional levels. Health diplomacy is vitally important in a global context, where health problems cross national borders and more new stakeholders appear every day, both within and outside the health sector. On the other hand, regional integration processes provide excellent opportunities for collective actions and solutions to many of the health challenges at the global level. In the current global context, the best conditions for dealing with many health challenges are found at the global level, but the regional and subregional spheres also play essential roles.
The region of Latin America and the Caribbean (LAC) consists of 26 countries or territories that occupy a territory of 7,412,000 square miles—almost 13% of the Earth’s land surface area; it extends from Mexico to Patagonia, where about 621 million people live (as of 2015), distributed among different ethnic groups. Geographically, it is divided into Mexico and Central America, the Caribbean, and South America, but it presents subregions with populations and cultures that are a little more homogenous, like the subregions of the Andes and the English Caribbean. By its characteristics, LAC has acquired increasing global political and economic importance.
In the 1960s, integration processes began in the region, including the creation of the Union of South American Nations (UNASUR), Mercosur, the Andean Community, the Caribbean Community (CARICOM), the Central American System, the Bolivarian Alliance for the Peoples of Our America (ALBA), the Amazon Cooperation Treaty Organization (ACTO), the Sistema Económico Latinoamericano y del Caribe (SELA), the Asociación Latinoamericana de Integración (ALADI), and finally, since 2010, the Community of Latin American and Caribbean States (Comunidad de Estados Latinoamericanos y Caribeños, or CELAC), which is the most comprehensive integrative organization.
While originally a mechanism for political and economic integration, health is now an important component of all the abovementioned integration processes, with growing social, political, and economic importance in each country and in the region, currently integrating the most important regional and global negotiations.
Joint protection against endemic diseases and epidemics, as well as noncommunicable diseases, coordination of border health care, joint action on the international scene (particularly in multilateral organizations such as the United Nations and its main agencies), and the sectoral economic importance of health are among the main situations and initiatives related to health diplomacy in these integration processes.
The effectiveness of integration actions—and health within those actions—varies according to the political orientations of the national governments in each conjuncture, amplifying or reducing the spectrum of activities performed. The complexity of both the present and future of this rich political process of regional health diplomacy is also very important for global health governance (GHG).

There is one common health objective by all nations, as stated in the constitution of the World Health Organization of 1947: the progress toward the best feasible level of health for all people. This goal captures the concept of health equity: fair distribution of unequal health. However, 70 years later, this common global objective has never been measured. Most of the available literature focuses on measuring health inequalities, not inequities, and tends to concentrate on comparisons among population subgroups, specific health risks, diseases, or health services, thereby indirectly contributing to the high fragmentation of health policies, actions, and even constituencies and resulting in competition for funds and/or priority.
A method to identify standards for the best feasible levels of health through criteria of healthy, replicable, and sustainable (HRS) models is needed. The avoidable death toll has not improved significantly since the 1970s. Younger age groups (though gradually shifting toward older age groups) and women are most affected. Data analysis of smaller sample units (such as provinces, states, counties, or municipalities) increases the sensitivity of measurement and detects higher levels of health inequity.
Most of the burden of health inequity takes place in countries with levels of income per capita below the average of the HRS countries, which is called the “dignity threshold” (the economic condition threshold necessary to enjoy the best feasible levels of health). Based on this threshold, it is possible to estimate the necessary distribution of the world’s resources compatible with the universal right to health—“the equity curve.” Income above the upper thresholds, and hence wealth accumulation, prevents others from living in conditions of dignity compatible with the universal right to health, is correlated with a carbon footprint above the ethical sustainable threshold, and does not translate into better health nor well-being. The international redistribution of wealth required to enable all nations to have at least an average per capita income above the dignity threshold would be around 8%, much higher than the present, nonbinding, and volatile levels of international cooperation, which currently lack an equity approach.
At subnational levels, the burden of health inequity can be the most sensitive barometer of socioeconomic justice among territories and the population, informing and directing fiscal and territorial equity schemes to enable all people within and between nations to enjoy the universal right to health. HRS models can also inspire lifestyles, political, and economic frameworks that increase efficiency, replicability, and sustainability of ethical well-being without undermining the rights of others in present and future generations.
Health for All and Primary Health Care, 1978–2018: A Historical Perspective on Policies and Programs Over 40 Years
Susan B. Rifkin
In 1978, at an international conference in Kazakhstan, the World Health Organization (WHO) and the United Nations Children’s Fund put forward a policy proposal entitled “Primary Health Care” (PHC). Adopted by all the World Health Organization member states, the proposal catalyzed ideas and experiences by which governments and people began to change their views about how good health was obtained and sustained. The Declaration of Alma-Ata (as it is known, after the city in which the conference was held) committed member states to take action to achieve the WHO definition of health as “state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” Arguing that good health was not merely the result of biomedical advances, health-services provision, and professional care, the declaration stated that health was a human right, that the inequality of health status among the world’s populations was unacceptable, and that people had a right and duty to become involved in the planning and implementation of their own healthcare. It proposed that this policy be supported through collaboration with other government sectors to ensure that health was recognized as a key to development planning.
Under the banner call “Health for All by the Year 2000,” WHO and the United Nations Children’s Fund set out to turn their vision for improving health into practice. They confronted a number of critical challenges. These included defining PHC and translating PHC into practice, developing frameworks to translate equity into action, experiencing both the potential and the limitations of community participation in helping to achieve the WHO definition of health, and seeking the necessary financing to support the transformation of health systems. These challenges were taken up by global, national, and nongovernmental organization programs in efforts to balance the PHC vision with the realities of health-service delivery. The implementation of these programs had varying degrees of success and failure. In the future, PHC will need to address to critical concerns, the first of which is how to address the pressing health issues of the early 21st century, including climate change, control of noncommunicable diseases, global health emergencies, and the cost and effectiveness of humanitarian aid in the light of increasing violent disturbances and issues around global governance. The second is how PHC will influence policies emerging from the increasing understanding that health interventions should be implemented in the context of complexity rather than as linear, predictable solutions.

There is a broad consensus that the health of an individual or population is not influenced solely by the efforts of the formal health sector; rather, it is also defined by the conditions of daily life as well as the inputs, intentional or not, of various stakeholders and policies. The recognition that health outcomes and inequity in health extend beyond the health sector across many social and government sectors has led to the emergence of a comprehensive policy perspective known as Health in All Policies (HiAP). Building on earlier concepts and principles outlined in the Alma-Ata Declaration (1978) and the Ottawa Charter for Health Promotion (1986), HiAP is a collaborative approach to public policies across sectors that systematically takes into account the health implications of decisions, seeks synergies, and avoids harmful health impacts in order to improve population health and health equity. Health in All Policies has become particularly relevant in light of the adoption of the 2030 Agenda for Sustainable Development and the 17 Sustainable Development Goals (SDGs), as achieving the goals of the agenda requires policy coherence and collaboration across sectors. Given that local governments are ideally positioned to encourage and galvanize partnerships between a diversity of local stakeholders, the implementation of HiAP at the local level is seen as a powerful approach to advancing health and achieving the SDGs through scaled-up initiatives. As there is no single model for the development and implementation of HiAP, it is critical to examine the different experiences across countries that have garnered success in order to identify best practices. The Region of the Americas has made much progress in advancing the HiAP approach, and as such much can be learned from analyzing implementation at country level thus far. Specific initiatives of the Americas may highlight key examples of local action for HiAP and should be taken into consideration for future implementation. Moving forward, it will be important to consider bottom up approaches that directly address the wider determinants of health and health equity.

Since the early 1990s, health policy in Latin America has focused on reform in most countries with the explicit purpose to increase access, decrease inequity, and provide financial protection. Basically, two different and opposed models of reform have been implemented: the Universal Health Coverage (UHC) model and the Single Universal Health System model. The essential characteristics of Latin American UHC are that health care is commodified by the introduction of competition that depends, in turn, on the payer/provider split, free choice, and pre-priced health service plans. In this framework, insurance, be it public or private, is crucial to assuring market solvency, because health needs not backed by purchasing power do not constitute a market that is particularly important in the Latin American region, the most unequal in the world. The Single Universal Health System (in Spanish, Sistema Universal de Salud, SUS) model is a model inspired by the principles of social justice and egalitarian, universal social rights. Characteristically funded by tax revenues, it makes provision of health services to the whole population a responsibility of the State and a universal citizens’ entitlement, independent of individual ability to pay or prior contributions. It considers health to be a public good that, for reasons of efficiency and equity, the market cannot provide. Everyone is entitled, as a right, to free care financed by the State.
Given that health system reform occurs in specific historical contexts, these models have had different results in each country. In order to highlight the concrete reform outcomes, the following issues need be addressed: the political scenario and the stakeholders involved; the previous health system and the relative strength of the public and private sectors; coverage achieved by public institutions or insurance, public or private; the different health packages existing within each country; the institutional (re)organization; and the relative importance of public health actions. An analysis is needed of the UHC reforms in Chile, Colombia, and Mexico, on the one hand; and the Single Universal Health System in Brazil, Venezuela, and Cuba on the other.
The UHC model in practice tends to increase inequity in access, create new bureaucratic barriers to timely care, fail to provide financial protection, and leads to deteriorated public health measures. It has also created new powerful private sector stakeholders, particularly in Chile and Colombia, while in Mexico the predominance of a strong public sector has “crowed-out” the private one. The Single Universal Health System has significantly increased access for millions that before reform had almost no access and has also strengthened public health actions. However, the strong preexisting private sector providers have profited from the public-sector purchases of complex medical services. Private health insurance has also increased among the upper middle class and workers belonging to strong labor unions.

The health status of refugees and asylum seekers varies significantly across the European region. Differences are attributed to the political nature of the legal categories of “asylum seeker” and “refugee”; the wide disparities in national health services; and the diversity in individual characteristics of this population including age, gender, socioeconomic background, country of origin, ethnicity, language proficiency, migration trajectory, and legal status. Refugees are considered to be at risk of being or becoming relatively “unhealthy migrants” compared to those migrating on the basis of economic motives, who are characterized by the “healthy migrant effect.” Refugees and asylum seekers are at risk to the drivers of declining health associated with settlement such as poor diet and housing. Restricted access to health care whether from legal, economic, cultural, or language barriers is another likely cause of declining health status. There is also evidence to suggest that the “embodiment” of the experience of exclusion and marginalization that refugee and asylum seekers face in countries of resettlement significantly drives decrements in the health status of this population.

At the end of 2016, there were approximately 36.7 million people living with HIV worldwide with 1.6 million people being newly infected. In the same year, 1 million people died from HIV-related causes globally. The vast prevalence of HIV calls for an urgent need to develop and implement prevention programs aimed at reducing risk behaviors. Bronfenbrenner’s socio-ecological model provides an organizing framework to discuss HIV prevention interventions implemented at the individual, relational, community, and societal level. Historically, many interventions in the field of public health have targeted the individual level. Individual-level interventions promote behavior change by enhancing HIV knowledge, attitudes, and beliefs and by motivating the adoption of preventative behaviors. Relational-level interventions focus on behavior change by using peers, partners, or family members to encourage HIV-preventative practices. At the community-level, prevention interventions aim to reduce HIV vulnerability by changing HIV-risk behaviors within schools, workplaces, or neighborhoods. Lastly, societal interventions attempt to change policies and laws to enable HIV-preventative practices.
While previous interventions implemented in each of these domains have proven to be effective, a multipronged approach to HIV prevention is needed such that it tackles the complex interplay between the individual and their social and physical environment. Ideally, a multipronged intervention strategy would consist of interventions at different levels that complement each other to synergistically reinforce risk reduction while simultaneously creating an environment that promotes behavior change. Multilevel interventions provide a promising avenue for researchers and program developers to consider all levels of influences on an individual’s behavior and design a comprehensive HIV risk-reduction program.

As a result of climate change, workers are at increased risk to their health and safety. Workers, especially those who work outdoors or in already-hot indoor environments, are at increased risk of heat stress and other heat-related disorders, occupational injuries, and reduced productivity at work. Increased ambient temperatures may contribute to chronic kidney disease of unknown etiology among workers. A variety of approaches have been developed to measure and assess workers’ occupational heat exposure and their risk of heat-related disorders. In addition, increased ambient temperature may increase worker exposure to hazardous chemicals and the adverse effects of chemicals on workers’ health. Global warming will influence the distribution of weeds, insect pests, and pathogens, changing the types and amounts of pesticides used and thereby affecting the health of agricultural workers and others. Global warming is increasing ground-level ozone concentrations, with adverse effects on outdoor workers and others, as well. Extreme weather events related to climate change pose injury risks to rescue and recovery workers. Reducing the risks of work-related illnesses and injuries from climate change requires a three-pronged approach: (1) mitigating the production of greenhouse gases, the primary cause of climate change; (2) implementing adaptation measures to address the overall consequences of climate change; and (3) implementing improved measures for occupational health and safety.

The psychosocial well-being of migrant children has become an urgent issue facing many Western countries as the number of migrant children in the population increases rapidly and health-care systems struggle to support them. Often, these children arrive with extensive exposure to trauma and loss before facing additional stressors in the host country. Yet, these children do not access mental health support even when available due to multiple barriers. These barriers include cultural and linguistic barriers, the primacy of resettlement needs, and the stigma attached to mental health illness. In order to improve mental health services for migrant children, there is a need to move away from focusing on trauma and mental health symptoms and to look instead at migrant children’s well-being across multiple domains, including activities that can promote or diminish psychological well-being. Trauma Systems Therapy for Refugees (TST-R) is an example of an approach that has succeeded in overcoming these barriers by adopting a culturally relevant and comprehensive approach to mental health care.
People who are forcibly displaced are forced to flee by serious threats to fundamental human rights, caused by factors such as persecution, armed conflict, and indiscriminate violence. Contemporary drivers of forced displacement are increasingly complex and interrelated. They include population growth, food insecurity, and water scarcity, at times compounded and multiplied by the effects of climate change. A refugee is someone who fled his or her home and country owing to “a well-founded fear of persecution because of his/her race, religion, nationality, membership in a particular social group, or political opinion,” according to the United Nations 1951 Refugee Convention. Internally displaced persons (IDPs) are people who have not crossed an international border but were forced to move to a different region than the one they call home within their own country. People who cannot return home without serious risk to their human rights have specific needs.
Forced displacement, both within a country and to other countries, is a major life event that abruptly changes environmental living conditions, such as social networks, language, and cultural environment of the displaced populations. The changes in environmental living conditions and disruptions in life challenge both the individual and the families of the displaced persons. Both types of forced displacement challenge adaptational mechanisms of individuals and families. Accordingly, the challenges can contribute to changes in mental health and mental disorders. However, estimates of mental health, mental disorders, and mental health determinants vary across and between forcibly displaced persons. This heterogeneity in estimates is associated with differences between refugee groups and with methodological difficulties in assessing refugees’ mental health. Instruments to assess mental health need to be culture-grounded and gender-sensitive to capture the scope and extent of refugees’ mental health and mental disorders. Based on reliable and valid instrument needs for assessing mental health and mental disorders, determinants can be identified and intervention can be developed and evaluated.

There are over 230 million international migrants worldwide, and this number continues to grow. Migrants tend to have limited access to and knowledge about resources and preventative care in their communities of reception, but nonetheless they are often in better health by many measures compared with native-born people in their communities of reception and with the people they left behind at their place of origin. With time since arrival, however, immigrants’ health advantages often dissipate and they experience increases in health problems, especially obesity and diabetes, which are chronic diseases that are increasingly prevalent in the overall population as well and are associated with multiple co-morbidities and limitations. It may be that immigrants have specific health endowments leading to these health patterns, or that the processes involved in migration, including exposure to new environments, behavioral change, and stress of migration may also affect risks of obesity and other chronic conditions. Understanding the health patterns of migrants can be useful in identifying their specific health needs, as well as contributing to our understanding of how specific environments, changes in environments, and individual health endowments interplay to shape the long-term health of populations.
There are an estimated 300 million indigenous peoples worldwide. Although there is ample evidence of worse health and social outcomes for the majority of indigenous peoples, compared to their non-indigenous counterparts, there has yet to be a review of racism as a determinant of indigenous health using global literature. Racism constitutes unfair and avoidable disparities in power, resources, capacities, or opportunities centered on ethnic, racial, religious, or cultural differences that can occur at three levels: internalized, interpersonal, or systemic. For indigenous peoples this is closely related to ongoing processes of colonization. Available research suggests that at least a third of indigenous adults experience racism at least once during their lives and that about a fifth of indigenous children experience racism. For indigenous peoples, racism has been associated with a considerable range of health outcomes, including psychological distress, anxiety, depression, suicide, posttraumatic stress disorder, asthma, physical illness, obesity, cardiovascular disease, increased blood pressure, excess body fat, poor sleep, reduced general physical and mental health, and poor oral health, as well as increased alcohol, tobacco, and marijuana use and underutilization of medical and mental healthcare services. Disparities in medical care experienced by indigenous patients compared to non-indigenous patients have also been found. Existing studies indicate that avoidant and passive coping tends to exacerbate the detrimental health impacts of racism for indigenous peoples, whereas active coping ameliorates the ill-health effects of racism. Reducing individual and interpersonal racism can be achieved by (a) providing accurate information and improving awareness of the nature of racism and racial bias; (b) activating values of fairness, reconciling incompatible beliefs, and developing antiracist motivation; (c) fostering empathy and perspective-taking and confidence in regulating emotional responses; (d) improving comfort with other groups and reducing anxiety; and (e) reinforcing antiracist social norms and highlighting personal accountability. There are five key areas for combating systemic racism in organizations and institutions: (a) institutional accountability; (b) diversity in human resources; (c) community partnership; (d) antiracism and cultural competence training; and (e) research and evaluation.

The indigenous peoples of Europe and Russia comprise the Inuit in Greenland, the Sami in northern Norway, Sweden, and Finland, and more than 40 officially recognized ethnic groups in northern Russia. While the health of the Inuit and Sami has been well studied, information about the health of the indigenous peoples of Russia is considerably scarcer. The article presents an outline of regional studies of population health and summarizes the major public health challenges that face the indigenous peoples of the North. The overall health of the Sami is, by and large, comparable to that of their non-indigenous neighbors in northern Scandinavia; the health of the Inuit is similar across Greenland and North America, though far less favorable than that of the populations of Denmark, southern Canada, and the lower 48 American states; the health of the indigenous peoples of the Russian north is poor, due partly to poverty and alcohol.
The People’s Health Movement (PHM) is a vibrant, global network bringing together grassroots health activists; civil society organizations; issue-based networks; academic institutions; and individuals from around the world, particularly the Global South. Since its inception in 2000, PHM has played a significant role in revitalizing Health for All (HFA) initiatives; and addressing underlying health determinants with a social justice perspective at global, national, and local levels. Members engage critically and constructively in health initiatives, health policy advocacy, and action. They undertake capacity building of community activists to participate in monitoring health-related policies and in governance of health systems. They play a crucial role in keeping Comprehensive Primary Health Care (CPHC) as a strategy to strengthen public health systems; in developing mechanisms to address the societal or social determinants of health; and in ensuring that people’s voices are part of decision making processes. PHM has an evolving presence in over 80 countries worldwide, consisting of groups of individuals and/or well-established circles with their own governance and information-sharing mechanisms. Additionally, there are issue-based circles across different countries.

Vaccination is one of the greatest public health successes. With sanitation and clean water, vaccines are estimated to have saved more lives over the past 100 years than any other health intervention. Vaccination not only protects the individual, but also, in many instances, provides community protection against vaccine-preventable diseases through herd immunity. To reduce the risk of vaccine-preventable diseases, vaccination programs rely upon reaching and sustaining high coverage rates, but paradoxically, because of the success of vaccination, new generations are often unaware of the risks of these serious diseases and their concerns now concentrate on the perceived risk of individual vaccines. Over the past decades, several vaccine controversies have occurred worldwide, generating concerns about vaccine adverse effects and eroding trust in health authorities, experts, and science. Gaps in vaccination coverage can, in part, be attributed to vaccine hesitancy and not just to “supply side issues” such as access to vaccination services and affordability.
The concept of vaccine hesitancy is now commonly used in the discourse around vaccine acceptance. The World Health Organization defines vaccine hesitancy as “lack of acceptance of vaccines despite availability of vaccination services. Vaccine hesitancy is complex and context specific, varying across time, place and vaccines.” A vaccine-hesitant person can delay, be reluctant but still accept, or refuse one, some, or all vaccines. Technical, psychological, sociocultural, political, and economic factors can contribute to vaccine hesitancy. At the individual level, recent reviews have focused on factors associated with vaccination acceptance or refusal, identifying determinants such as fear of side effects, perceptions around health and prevention of disease and a preference for “natural” health, low perception of the efficacy and usefulness of vaccines, negative past experiences with vaccination services, and lack of awareness or knowledge about vaccination.
Very few interventions have been shown to be effective in reducing vaccine hesitancy. Most of the studies have only focused on metrics of vaccine uptake and refusal to evaluate interventions aimed at enhancing vaccine acceptance, which makes it difficult to assess their potential effectiveness to address vaccine hesitancy. In addition, despite the complex nature of vaccination decision-making, the majority of public health interventions to promote vaccination are designed with the assumption that vaccine hesitancy is due to lack or inadequate knowledge about vaccines (the “knowledge-deficit” or “knowledge gap” approach). A key predictor of acceptance of a vaccine by a vaccine-hesitant person remains the recommendation for vaccination by a trusted healthcare provider. When providers communicate effectively about the value and need for vaccinations and vaccine safety, people are more confident in their decisions. However, to do this well, healthcare providers must be confident themselves about the safety, effectiveness, and importance of vaccination, and recent research has shown that a proportion of healthcare providers are vaccine-hesitant in their professional and personal lives. Effective strategies to address vaccine hesitancy among these hesitant providers have yet to be identified. A better understanding of the dynamics of the underlying determinants of vaccine hesitancy is critical for effective tailored interventions to be designed for both the public and healthcare providers.

Violence is a problem that accompanies the trajectory of humanity, but it presents itself in different ways in each society and throughout its historical development. Despite having different meanings according to the field of knowledge from which it is addressed and the institutions that tackle it, there are some common elements in the definition of this phenomenon. It is acknowledged as the intentional use of force and power by individuals, groups, classes, or countries to impose themselves on others, causing harm and limiting or denying rights. Its most frequent and visible forms include homicides, suicides, war, and terrorism, but violence is also articulated and manifested in less visible forms, such as gender violence, domestic violence, and enforced disappearances.
Although attention to the consequences of different forms of violence has always been part of health services, its formal and global inclusion in health sector policies and guidelines is very recent. It was only in 1996 that the World Health Organization acknowledged it as a priority in the health programs of all countries. Violence affects individual and collective health; causes deaths, injuries, and physical and mental trauma; decreases the quality of life; and impairs the well-being of people, communities, and nations. At the same time, violence poses problems for health researchers trying to understand the complexity of its causes, its dynamics, and the different ways of dealing with it. It also poses serious challenges to health systems and services for the care of victims and perpetrators and the formulation of interdisciplinary, multi-professional, inter-sectoral, and socially articulated confrontation and prevention policies and programs.
