15 Vaccines induce the body’s adaptive immune response via generating protective antibodies against possible future infections. 14 Vaccination is likely to remain the most effective prophylactic measure for effective public health response. 13 Many drugs and therapeutic compounds have been recommended in the fight against COVID-19, but these function only as supportive treatments. Global efforts to combat COVID-19 primarily depend on preventive measures adopted by individuals to reduce the likelihood of infection transmission. Given persistent challenges such as public mistrust and low acceptance even among healthcare workers, 12 there remains a need to investigate and document safety data of COVID-19 vaccines in varied settings. Vaccine uptake depends on public acceptance. 11 Arguably, the low attribution of SAEs speaks to the relative safety of the vaccines. S vaccine– four SAEs with none related to the vaccine Comirnaty (BNT162b1) vaccine – five SAEs reported and Covaxin (BBV152) vaccine – one SAE was identified. Less frequently, serious adverse events (SAE) were reported in four vaccine trials: COVID-19 Vaccine AstraZeneca (AZD1222)-168 SAEs with three events shown to be related to the vaccine Ad26.COV2. 10 Reports have identified common vaccine-related side effects such as pain at the injection site, fever, myalgia, fatigue, and headache. 9ĬOVID-19 vaccines provided definitive therapy, reducing illness and hospitalizations from COVID-19 infection, thus potentially ameliorating the course and impact of the COVID-19 pandemic. 8 Until the advent of vaccines in 2021, COVID-19 prevention and control measures in the community relied on a complementary suite of non-pharmaceutical interventions, including hand hygiene, use of personal protective equipment, crowd avoidance, social distancing, community lockdowns, and travel restrictions. 7 WHO declared the associated disease, coronavirus disease-2019 (COVID-19), a pandemic in March 2020. 5 The Coronavirus Study Group of the International Committee on Taxonomy of Viruses designated this virus as the “severe acute respiratory syndrome coronavirus-2” (SARS-CoV-2), 6 the seventh known coronavirus to infect humans. 2–4 In early 2020, the World Health Organization (WHO) designated this fast-spreading virus, with an incubation period ranging from 1–14 days (average of five days), as the 2019 novel coronavirus (2019-nCoV). In late 2019, patients from Wuhan first experienced pneumonia due to a novel coronavirus subsequently identified as a human beta coronavirus (HβCoV) of zoonotic origin, 1 which is predominantly spread directly or indirectly via respiratory droplets and aerosols released when infected persons cough, sneeze, talk, or sing.
