Knowledge, attitudes and barriers to uptake of COVID-19 vaccine in Uganda, February 2021.

INTRODUCTION

Uganda planned to start its COVID-19 vaccination campaign in March 2021, prioritising healthcare workers, security personnel, elderly and people with comorbidities. However, the willingness to receive the vaccine and potential barriers and hindrances were unknown. To understand the barriers to uptake of the COVID-19 vaccine prior to its rollout, we explored the communities' knowledge, attitudes and barriers.

METHODS

We conducted a mixed-methods cross-sectional study in Kampala and Ankole subregions in February 2021. For the household survey, we used three-stage sampling to select three districts in each subregion and, thereafter, 12 villages per district. One adult in each household was interviewed. Additionally, we conducted focus group discussions and key informant interviews to explore knowledge, attitudes and barriers to COVID-19 vaccination. Modified Poisson regression was used to identify factors associated with willingness to receive to COVID-19 vaccine RESULTS: Among 1728 respondents, 52% were under 40 years old, and 67% were female. Fifty-nine percent of those who had heard of the vaccine primarly obtained information from radio and television (TV). Despite one-quarter reporting that they had heard that the vaccine could cause death or genetic changes, 85% were willing to receive it. Persons in the Kampala subregion were less willing than those in the Ankole subregion to take the vaccine (76% vs 94%, adjusted prevalence ratio (aPR)=0.85, 95% CI: 0.81 to 0.89). Trust in the effectiveness of non-vaccine COVID-19 preventive measures (aPR=0.89, 95% CI: 0.80 to 0.99), living in urban areas (aPR=0.84, 95% CI: 0.76 to 0.91) and lack of information on vaccine safety (aPR=0.91, 95% CI: 0.83 to 0.93) reduced interest in taking the vaccine.

CONCLUSIONS

Vaccine willingness was high despite some misinformation and safety concerns, which more prevalent in Kampala than in the Ankole subregion. While radio and TV were major sources of COVID-19 vaccine information, social media was the biggest propagator of COVID-19 vaccine misinformation. Therefore, providing credible information about vaccine safety could reinforce uptake, especially among urban residents. Additionally, local and national leaders should publicise their acceptance of vaccines and debunk misinformation.
