Background Vaccination has been recommended as one of the approaches for the control of COVID-19 pandemic. However, adequate vaccine coverage is critical to the effectiveness of the vaccine at population level. Data on acceptability of the vaccine in Ugandan urban areas are limited. This study examined the prevalence, factors associated with willingness to accept COVID-19 vaccine including reasons for not taking COVID-19 vaccine in a predominantly urban population of Wakiso, central Uganda. Methods Data were obtained from a cross-sectional study conducted between March 1st, 2021 and September 30th, 2021 in the urban population-based cohort of the Africa Medical and behavioral Sciences Organization (AMBSO). A Multivariable modified Poisson regression analysis was used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals of willingness to accept the COVID-19 vaccine. Results A total of 1,903 participants were enrolled in this study; 61% of whom were females. About 63% of participants indicated their willingness to accept the COVID-19 vaccine. Persons aged 13–19 years (aPR = 0.79; [95% CI: 0.74, 0.84]) or 20-29years (aPR = 0.93; [95% CI: 0.88, 0.98]) were less likely to accept the vaccine compared to persons aged 40–49 years. Persons with post-primary level of education (aPR = 1.05; [95% CI: 1.02, 1.09]) were more likely to accept the vaccine compared to persons with primary level of education. Additionally, students or individuals working in government (aPR = 1.13; [95% CI: 1.04, 1.23]) were more likely to accept the vaccine compared to individuals doing construction and Mechanic work as their main occupation. Reported reasons for not taking a COVID-19 vaccine included; concerns about side effects of the vaccine 154(57.0%), 64(23.7%) did not think the vaccines were effective, while 32(11.9%) did not like the vaccines. Conclusion A substantial proportion of individuals were not willing to accept the COVID-19 vaccine. Health education campaigns on vaccination within urban communities could help reduce COVID-19 vaccine misconceptions in the urban populations more especially the young and persons with low levels of formal education.

Modern contraceptive use has increased globally, but unmet needs persist in low- and middle-income countries. This study in Uganda aimed to examine the prevalence and factors influencing the use of short-acting reversible contraceptives (SARC) like pills and long-term methods such as intrauterine devices. Limited evidence exists on the use of SARC and long-term methods in Uganda. Data from the Africa Medical and Behavioural Sciences Organization (AMBSO) Population Health Surveillance (APHS) in Hoima and Wakiso districts were analysed. Among the 1642 women aged 15–49 years, the prevalence of modern contraceptive use was 30% for SARC, and 18% for long-term method. Women with formal education were three times more likely to use long-term methods than those without formal education, relative risk ratios (RRR), 3.1–3.4, (95%CI 1.2–8.2). Joint decision-making for contraceptive use increased SARC usage, RRR 1.4 (95%CI 1.1–1.8). Urbanization played a role, with women in more urbanized Wakiso district less likely to use any modern contraception, RRR 0.6–0.7 (95%CI 0.5–0.9) compared to those living in the less urbanized Hoima. About half of the women in the study used modern contraceptives and the use of SARC was almost twice that of long-term methods. Increased access to contraception education for all women of reproductive age could significantly improve the use of long-term methods which offer more reliable protection against unintended pregnancies. The findings shed light on the need to strengthen both general and sexuality education to girls and women and to tailor contraception access for all in need, for mobile semi-urban as well as rural women. Well-informed strategies that engage young men and male partners in informed decision-making for contraceptive use could enhance progress.

Background: Vaccination is essential for controlling the COVID-19 pandemic. However adequate vaccine coverage is a critical to the effectiveness of the vaccine at a population level. Data on to acceptability of the vaccine in Urban areas are limited. This study examined the prevalence, factors associated with willingness to receive COVID-19 vaccine and reasons for hesitancy in the predominantly urban Wakiso district of Uganda. Methods: Data were obtained from a cross-sectional study conducted from March 1st, 2021, to September 30th, 2021 in the urban population-based cohort of the Africa Medical and behavioral Sciences Organization (AMBSO). Multivariable modified Poisson regression analysis was used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals of willingness to accept the COVID-19 vaccine. Results: A total of 1,903 participants were enrolled in the study; 61% of whom were females. About 63% of participants indicated willingness to accept the COVID-19 vaccine. Younger age groups (13-19 and 20-29) were less likely to accept the vaccine compared to the persons ages 40-49 years (aPR=0.79; 95% CI: 0.74, 0.84 for the 13-19 years and 0.93; 95% CI: 0.88, 0.98 for age group 20-29, compared to those ages 40–49 years. Post-primary education (aPR=1.05; 95% CI: 1.02, 1.09 compared to primary level), being a students and government staff (APR=1.13; 95% CI: 1.04, 1.23 compared to construction and Mechanic workers) were associated with willingness to receive COVID-19 vaccine. Some of the reported reasons for hesitancy included; concerns about side effects 154(57.0%), about 64(23.7%) did not think the vaccines were effective, and those who did not like the vaccines 32(11.9%). Conclusion: A substantial proportion of individuals were not willingness to receive the COVID-19 vaccine. More effort is needed to reduce vaccine hesitancy, especially among the young and people with lower formal education.
