COVID-19 Vaccines:

A vaccine is a medical or biological preparation that activates the immune system in an individual to fight pathogens that enter the body. Killed or deactivated form of the pathogen, toxin, or surface protein are commonly used to prepare a vaccine. The process of administration of the vaccine is known as vaccination. For people to develop immunity or defense against the SARS-CoV-2 virus (the virus that causes COVID-19) and put an end to this pandemic, various COVID-19 vaccines have been developed, and some have also been approved for emergency use.

Basic knowledge and understanding of these vaccines are necessary before you choose to get vaccinated. Educating ourselves about the advantages, disadvantages, precautions, and side effects of these vaccines will avoid unnecessary panic. The two vaccines that are now being administered in India are Covishield and Covaxin. An individual's medical history and health condition should be greatly considered before getting these vaccines. Some people fear that COVID-19 vaccines can make them prone to COVID-19 infection. But these vaccines do not contain any live components of SARS-CoV-2 and are relatively safe.
