Context: Developing an effective vaccine for HIV/AIDS is a global endeavor requiring the participation of willing volunteers.

Aims: To evaluate the willingness of the global population to undergo vaccination and participate in clinical trials.

Methods: Following PRISMA guidelines, relevant studies published from January 2005 to December 2019 that reported quantitative, qualitative, and mixed analyses in peer-reviewed research papers were sought in the major databases. The inclusion criteria were that the studies be related to the willingness of participants to undergo HIV vaccination and submit to subsequent clinical trials, that they are in English, conducted in any geographic location, and published during the target period. The exclusion criteria were grey literature and studies involving the stakeholders, medical students or medical fraternities, seropositive parents with seronegative offspring, the vaccine’s biochemical, immunological, or financial aspects, and participants below the age of 16. Systematic reviews, letters to the editor, and case studies were also excluded.

Results: The selected databases initially yielded 334 articles, of which 27 remained after applying the inclusion and exclusion criteria. Demographic data, motivating factors, and the volunteers’ willingness levels were collected and analyzed.

Conclusions: This review offers guidance for future research, including a standardized scale to predict the willingness of potential volunteer groups.

Keywords: clinical trials; HIV; review; vaccination; volunteers; willingness.



Contexto: Desarrollar una vacuna efectiva para el VIH/SIDA es un esfuerzo global que requiere la participación de voluntarios dispuestos.

Objetivos: Evaluar la disposición de la población mundial a vacunarse y participar en ensayos clínicos.

Métodos: Siguiendo las pautas PRISMA, se buscaron en las principales bases de datos estudios relevantes publicados entre enero de 2005 y diciembre de 2019 que informaron análisis cuantitativos, cualitativos y mixtos en artículos de investigación revisados ​​por pares. Los criterios de inclusión fueron que los estudios estuvieran relacionados con la disposición de los participantes a vacunarse contra el VIH y someterse a ensayos clínicos posteriores, que estuvieran en inglés, realizados en cualquier ubicación geográfica y publicados durante el período objetivo. Los criterios de exclusión fueron literatura gris y estudios que involucraran a las partes interesadas, estudiantes de medicina o fraternidades médicas, padres seropositivos con hijos seronegativos, aspectos bioquímicos, inmunológicos o financieros de la vacuna, y participantes menores de 16 años. Revisiones sistemáticas, cartas al editor, y los estudios de casos también fueron excluidos.

Resultados: Las bases de datos seleccionadas arrojaron inicialmente 334 artículos, de los cuales quedaron 27 después de aplicar los criterios de inclusión y exclusión. Se recopilaron y analizaron datos demográficos, factores motivadores y niveles de disposición de los voluntarios.

Conclusiones: Esta revisión ofrece orientación para futuras investigaciones, incluida una escala estandarizada para predecir la disposición de los posibles grupos de voluntarios.

Palabras Clave: disposición; ensayos clínicos; VIH; revisión; vacunación; voluntarios.
