Perceptions of the COVID-19 Vaccine and Other Adult Vaccinations in Malawi: A Qualitative Assessment.

In Malawi, various brands of the COVID-19 vaccine have been offered to the population, but factors including fear of side effects or other risks, uncertainty about benefits, and misinformation created hesitancy toward them. In early 2022, 4% of Malawians were fully vaccinated for COVID-19. Despite multiple promotion efforts, by August 2022, COVID-19 vaccination nationwide was around 15%. To increase COVID-19 vaccination uptake, the research team collected qualitative data in 4 districts with vaccine coverage levels ranging from 1% to 11%. This data collection happened during a cholera outbreak that began in March 2022 and the vaccination efforts to address it. Study participants included male and female members of the general population, social workers, people with comorbidities, health workers, and community leaders (224 participants total, 47% female). In focus group discussions (n=27) and in-depth interviews (n=17), participants compared COVID-19 vaccines with other adult vaccines, such as cholera and tetanus toxoid. A thematic analysis identified themes related to 3 research questions on COVID-19 vaccine concerns, confidence, and delivery affecting uptake. Differences in promotion, delivery (oral versus injection), COVID-19 vaccine card structure, the various brands and boosters, and vaccines being described as required or optional all played a role in distinguishing COVID-19 vaccines from other vaccines and creating suspicion or indifference. Barriers to vaccination in general, such as rumors or knowledge gaps, were amplified by how novel the COVID-19 vaccines were perceived to be and the changing guidance provided over time. By April 2023, more targeted campaign efforts helped increase vaccination rates to 28%. The findings contribute information about how individuals conceptualize and make decisions about adult vaccination, which can, in turn, inform strategies to integrate COVID-19 promotion and delivery with other disease responses in Malawi as well as routine health services in similar settings.

Tropical Data: Approach and Methodology as Applied to Trachoma Prevalence Surveys.

PURPOSE: Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work to undertake those surveys. METHODS: Tropical Data is a consortium of partners that supports health ministries worldwide to conduct globally standardised prevalence surveys that conform to World Health Organization recommendations. Founding principles are health ministry ownership, partnership and collaboration, and quality assurance and quality control at every step of the survey process. Support covers survey planning, survey design, training, electronic data collection and fieldwork, and data management, analysis and dissemination. Methods are adapted to meet local context and needs. Customisations, operational research and integration of other diseases into routine trachoma surveys have also been supported. RESULTS: Between 29th February 2016 and 24th April 2023, 3373 trachoma surveys across 50 countries have been supported, resulting in 10,818,502 people being examined for trachoma. CONCLUSION: This health ministry-led, standardised approach, with support from the start to the end of the survey process, has helped all trachoma elimination stakeholders to know where interventions are needed, where interventions can be stopped, and when elimination as a public health problem has been achieved. Flexibility to meet specific country contexts, adaptation to changes in global guidance and adjustments in response to user feedback have facilitated innovation in evidence-based methodologies, and supported health ministries to strive for global disease control targets.
