Equity has become a key objective for the Pan American Health Organization (PAHO). This is the result of multidimensional movements with a history that can only be understood in the light of social relations that structure the processes we refer to as "health". From an initial concern for maritime trade to a current interest in the social determinants of health, PAHO has strengthened its efforts to make the concept of health equity the ultimate goal of its actions. The idea of health focused on the individual has given way to the idea of health for all people, which considers the differences between being and doing in the world. These changes have produced policies, analyses, and studies in which gender and cultural diversity are cross-cutting themes that must be considered in all planning and implementation of health policies in the Region of the Americas. This article discusses milestones on the road to health equity in the Region from a historical perspective.

Randomised experimental evaluation of a social media campaign to promote COVID-19 vaccination in Nigeria.

Background: The coronavirus disease 2019 (COVID-19) pandemic has challenged public health and behaviour change programmes, and has led to the development of innovative interventions and research. In low -and middle-income countries (LMICs) such as Nigeria, new strategies to promote vaccination, increase pro-vaccination social norms, and reduce vaccine hesitancy have been deployed through social media campaigns and evaluated using digital media platforms. Methods: We conducted two randomised experimental evaluations of social media content designed to promote COVID-19 vaccination and to complement research on a nationwide vaccination promotion campaign in Nigeria run in 2022. We conducted two studies in March and August 2022 among Nigerians drawn from 31 states that had not been targeted in the aforementioned nationwide campaign. We randomised the participants to either receive the pro-vaccination social media campaign or not and collected data at pre- and post-test time points to evaluate psychosocial predictors of vaccination and vaccination outcomes following the Theory of Change based on Diffusion of Innovations; the Social Norms Theory, and the Motivation, Opportunity, Ability (MOA) framework. Data were collected through a novel intervention delivery and data collection platform through social media. Results: We found that pro-vaccination social norms and vaccination rates increased, while vaccine hesitancy decreased among participants randomised to the social media intervention study arm. Conclusions: Social media campaigns are a promising approach to increasing vaccination at scale in LMICs, while social norms are an important factor in promoting vaccination, which is consistent with the Social Norms Theory. This study demonstrates the capability and potential of new social media-based data collection techniques. We describe implications for future vaccination campaigns and identify future research priorities in this area. Registration: Pan African Clinical Trial Registry: PACTR202310811597445.

Development and Evaluation of an Index to Measure the Ability to Get Vaccinated for COVID-19.

The COVID-19 pandemic has been an historic challenge to public health, and to behavior change programs. There have been challenges in promoting vaccination in LMICs, including Nigeria. One important hypothesis deserving consideration is the ability to obtain vaccination as a potential barrier to vaccination uptake. The MOA (motivation, opportunity, and ability) framework, as illustrated by multiple theories such as COM-B, EAST, and the Fogg model, is a primary theoretical basis for the evaluation of this ability as a factor in vaccination uptake. There is little research on measuring the ability to get vaccinated in LMICs, including on the role of all of the MOA framework. The aim of this study was to develop and evaluate an ability factors index measured through social media-based data collected in Nigeria in late 2021 and early 2022. We present findings from an online survey of 8574 Nigerians and highlight new social media-based data collection techniques in this research. This study found that a new ability factors index comprising 12 items was associated with vaccine uptake independent of measures capturing other components of the MOA framework. This index may serve as a valuable research instrument for future studies. We conclude that a person's perceived ability to get vaccinated, measured by a newly validated index, is related to vaccination uptake and hesitancy, and that more research should be conducted in this area.

Outcomes of a social media campaign to promote COVID-19 vaccination in Nigeria.

The COVID-19 pandemic has been an historic challenge to public health and behavior change programs. In low -and middle-income countries (LMICs) such as Nigeria, there have been challenges in promoting vaccination. Vaccine hesitancy and social norms related to vaccination may be important factors in promoting or inhibiting not only COVID vaccination, but other routine vaccinations as well. The aim of this study was to conduct a national-level quasi-experimental evaluation of a social media based COVID-19 vaccination promotion campaign in Nigeria run in 2022. We followed a longitudinal cohort of Nigerians (at baseline) drawn from all 37 states in Nigeria over a 10-month period. This was done at 3 time points to evaluate psychosocial predictors of vaccination and vaccination outcomes following a theory of change based on Diffusion of Innovations, Social Norms Theory, and the Motivation, Opportunity, Ability (MOA) Framework. In a quasi-experimental design, participants in 6 Nigerian states where the social media campaign was run (treatment) were compared to participants from non-treatment states. This study highlights new social media-based data collection techniques. The study found that vaccination rates increased in treatment states compared to non-treatment states, and that these effects were strongest between baseline and first follow up (December 2021 to March 2022). We also found that more pro-vaccination social norms at one time point are associated with higher vaccination rates at a later time point. Social media campaigns are a promising approach to increasing vaccination at scale in LMICs, and social norms are an important factor in promoting vaccination, which is consistent with the Social Norms Theory. We describe implications for future vaccination campaigns and identify future research priorities in this area.

RESUMEN Hoy en día la equidad es un objetivo central para la Organización Panamericana de la Salud (OPS). Este objetivo es el resultado de movimientos multidimensionales que tienen una historia y que sólo pueden comprenderse a la luz de las relaciones sociales que estructuran los procesos que llamamos de "salud". De una preocupación por el comercio marítimo a un interés por los determinantes sociales de la salud, la OPS ha fortalecido sus esfuerzos por poner en el centro de sus acciones la idea de la equidad en salud como fin último. Se ha pasado de una idea de salud enfocada en el individuo, a una idea de salud para todas las personas, que contemple las diferencias de ser y hacer en el mundo. Estos cambios han producido políticas, análisis y estudios donde el género y la diversidad cultural son ejes transversales que deben ser contemplados en toda planificación y ejecución de políticas de salud en la Región de las Américas. En este artículo se analizan momentos clave en el camino hacia la equidad en salud en la Región desde una perspectiva histórica.
