Clinical trials, Covid-19, VaccinesAbstract
Vaccines are biological products that can help body to acquire immunity against pathogen without occurrence of infection. During clinical trials, vaccines are tested in volunteers to ensure safety and effectiveness. As a part of phase 4 clinical stage, adverse effects are monitored regularly by the licensing authority. The benefit of vaccination is to reduce the risk of death and severe disease. Evidence suggests that it is very common to get side effects after covid-19 vaccination. These side effects usually disappear after few days of vaccination. The main aim of this review is to provide an overview of covid-19 vaccines in the present scenario.
