COVID-19 vaccine acceptance and hesitancy in low- and middle-income countries.

Widespread acceptance of COVID-19 vaccines is crucial for achieving sufficient immunization coverage to end the global pandemic, yet few studies have investigated COVID-19 vaccination attitudes in lower-income countries, where large-scale vaccination is just beginning. We analyze COVID-19 vaccine acceptance across 15 survey samples covering 10 low- and middle-income countries (LMICs) in Asia, Africa and South America, Russia (an upper-middle-income country) and the United States, including a total of 44,260 individuals. We find considerably higher willingness to take a COVID-19 vaccine in our LMIC samples (mean 80.3%; median 78%; range 30.1 percentage points) compared with the United States (mean 64.6%) and Russia (mean 30.4%). Vaccine acceptance in LMICs is primarily explained by an interest in personal protection against COVID-19, while concern about side effects is the most common reason for hesitancy. Health workers are the most trusted sources of guidance about COVID-19 vaccines. Evidence from this sample of LMICs suggests that prioritizing vaccine distribution to the Global South should yield high returns in advancing global immunization coverage. Vaccination campaigns should focus on translating the high levels of stated acceptance into actual uptake. Messages highlighting vaccine efficacy and safety, delivered by healthcare workers, could be effective for addressing any remaining hesitancy in the analyzed LMICs.

Caracterización del Comportamiento Sexual y Reproductivo y Acceso A los Servicios de Salud, de los Estudiantes de la Facultad de Ciencias Médicas de la Universidad de Cuenca / Characterization of Sexual and Reproductive Behavior and Access to Health Services, of the Students of the Faculty of Medical Sciences of the University of Cuenca

ANTECEDENTES: La población universitaria es principal-mente joven y por lo tanto expuesta a factores que puede generar efectos adversos en salud sexual y re-productiva, que conllevan a un bajo rendimiento académico e inclusive a la deserción estudiantil. OBJETIVO: Caracterizar el comportamiento sexual y re-productivo y las necesidades en salud de los en estudiantes de la Facultad de Ciencias Médicas de la Universidad de Cuenca. METODOLOGÍA: Tipo de estudio descriptivo. Universo: 3 265 estudiantes de la Facultad de Ciencias Médicas de la Universidad de Cuenca, en el período lectivo septiembre 2014- Febrero 2015. Muestra: fue aleatorizada por conglomerados (carrera y cursos) en las tres escue-las de la facultad de Ciencias Médicas. RESULTADOS: De los estudiantes encuestados, el 44.7% fueron de la escuela de medicina de 27.7% de enfermería, 27.7% tecnología médica; 68.6% mujeres y 31.4% varones, con una edad media de 21 años para ambos grupos; la mayoría son solteros 87.7%, mestizos 94.1% y heterosexuales 97.2%, que residen en zona urbana 81.5%. El 45.7% de las mujeres y el 70.1% de los varones son sexualmente activos, 15% son padres de familia, el 81,6% ha usado un método anticonceptivo MAC, sin embargo el uso consistente es de 55.1%. 66.2% de los encuestados ha acudido a un médico el último año; el 77.3% maneja suficiente información para la prevención de un embarazo y el 79.7% para la prevención de ITS. CONCLUSIONES: Pese a que los estudiantes tienen in-formación en sexualidad y acceden a los servicios de salud, los efectos adversos en salud sexual y reproduc-tiva son identificados como un problema que conlleva a deserción estudiantil y bajo rendimiento académico. Las principales soluciones para combatir los efectos adversos, incluyen: mejorar la calidad de información, fortalecer el acceso a servicios integrales de salud, generar espacios saludables.

OBJECTIVE: To characterize sexual and reproductive be-havior and health needs of students in the Faculty of Medical Sciences of the University of Cuenca. METHOD: descriptive study type. Universe: 3265 students of the Faculty of Medical Sciences of the University of Cuenca, in the academic year in September 2014 in February 2015. Sample: was randomized by cluster (ca-reer and courses) in the three schools of the Faculty of Medical Sciences. RESULTS: Of all the surveyed students, 44.7% were from medical school, nursing 27.7%, 27.7% medical technology; 68.6% female and 31.4% male, with a mean age of 21 years; most are unmarried 87.7%, 94.1% are heterosexual, mestizos 97.2% residing in urban areas 81.5%. 45.7% of the women and 70.1% of males are sexually active, 15% are parents, 81.6% have used a contraceptive, however the consistent use of contra-ceptives is 55.1%. 66.2% of respondents have visited a doctor last year; 77.3% handle sufficient information for the prevention of pregnancy and 79.7% for STD prevention. CONCLUSIONS: Although students have information on sexuality and access to health services, adverse effects on sexual and reproductive health are identified as a problem that leads to student dropout and low aca-demic performance. The main solutions to combat the adverse effects include: improving the quality of infor-mation, enhance access to comprehensive health ser-vices, generating healthy spaces.
