FAQs Surrounding COVID-19 Vaccine


Out of the multiple vaccines available, how is one or more vaccines chosen for administration?

The safety and efficacy data from clinical trials of vaccine candidates are examined by the Drug regulator of our country before granting the license for the same. Hence, all the COVID-19 vaccines that receive license will have comparable safety and efficacy.

However, it must be ensured that the entire schedule of vaccination is completed by only one type of vaccine as different COVID-19 vaccines are not interchangeable.

Can a person presently having COVID-19 (confirmed or suspected) infection be vaccinated?

A person with confirmed or suspected COVID-19 infection may increase the risk of spreading the same to others at the vaccination site. Also, we do not know how effective the vaccine will be in such a situation when one is already having an active infection. For this reason, infected individuals should defer vaccination for 14 days after symptom resolution.
