The "Severe Acute Respiratory Syndrome Coronavirus 2" (SARS-CoV-2)
disease has resulted in a worldwide challenging and dangerous pandemic,
COVID-19 vaccines have beenpreventing serious morbidities and mortality
associated with the infection. However, in addition to these findings, some
unusualadverse effects have been reported.
Vaccine side effects are common. They demonstrate that immunizations are
effective and that the immune system is responding. For assessing the safety
of the vaccine, side effects and adverse events are fundamental.
To evaluate side effects of corona virus vaccines
A prospective cohort study using a pre‐organized questionnaire
encompassing, demographic, general health, the status of SARS‐CoV‐2
infection, vaccination, associated adverse events, breakthrough infections and
their IgG anti-spike antibody titers; in a population comprising 200
individuals aged 18 and above who received 2 doses of one of covid-19
The responses of 200 individuals were analyzed statistically. Revealing that
most utilized vaccine in the population was the Pfeizer-BioNtech vaccine.
Side effects were generally subtle, in all three vaccines, with no serious
adeverse events. Oxford-AstraZeneca
vaccine however, showed fiercer side effects compared to the other two
vaccines. Several side effects were more prevalent in male gender, but there
was no noteworthy correlation with other factors.
COVID-19 vaccinations appear to be safe. Although adverse events are rare
on a worldwide scale, a large proportion of the world's population will be
exposed to these vaccines. for this reason, their safety and tolerance must be
carefully evaluated.
