Abstract

ABSTRACT
Introduction. Little is documented on the frequency, severity, and factors associated with Covid 19 vaccine side effects post vaccination campaigns in Cameroon. The main objective of the study was to evaluate post COVID19 vaccination side effects of approved government anti-covid vaccines occurrence, frequency of and severity in Bangourain Health District, Cameroon. Methodology. A cross sectional study was conducted. The data collection was collected for 4weeks from the 15 May to 15 June, 2022. Our sample size was consecutive. We included in our study everybody who has received at least one dose of any of the Covid 19 vaccines be it Sinopharm, Johnson-Johnson or Astra-Zenecca and who accepted to take part in the study. Results. A total of 162 participants were enrolled in the study with mean age of 42.77. The frequency of occurrence of side effects to Covid-19 vaccine was 66.7% for the first dose, 50.5% for the second dose and 54.8% for the third dose, all vaccine types combined. The most common side effects reported were local pain (84.67%), itch at injection site (15.38%), fever (15.38%), fatigue (15.38%) and functional Impotence (15.38%) for Sinopharm; local pains (68.18%), stiffness of arms (36.36%), Fatigue (36.36%), Headache (31.82%), and fever (25.00%) for AstraZeneca and local pains (90.20%), fatigue (31.37%), Headache (25.49%), fever (19.61%) and Itch at injection site (15.69%) for Johnson and Johnson. Conclusion. Irrespective of the type and dose of vaccine, many participants developed side effects after administration of Covid-19 vaccine, most of which are similar to those reported by manufacturers with certain disparities observed in the frequency of occurrence.
