Recommendations and effect of COVID-19 vaccines

Abstract

COVID-19 virus infection 2019 (COVID-19) is the disease caused by the SARS-CoV-2 virus (severe acute respiratory syndrome coronavirus-2). Several studies detect that old aged persons as well as people with risk factors such as chronic hepatic disease, cirrhotic liver, cardiac illness, over bodyweight, and compromised immune systems due to other diseases or drugs are more likely to have a higher mortality rate from corona virus infection. Safe and effective vaccination has become a key tool to prevent the new corona virus illness. The world is racing to develop and produce COVID-19 vaccines. Healthcare workers were given priority for early immunization as they are at great risk of infection and may influence vaccine uptake in the general population. COVID-19 vaccines were well tolerated, secure, and create a resistance reaction against the infection in most cases. Most side effects that occurred after vaccinations were mild to moderate, which showed the building of a resistance by the body for protection. Vaccination apprehension is one of the major hurdles to world health. It is important to Know about a vaccine's unfavorable impacts and efficacy to improve public vaccine acceptance.
