Coronavirus Vaccine: Will you be needing a COVID-19 vaccine next year? Here’s what doctors have to say


Vaccine boosters have gained a lot of momentum in recent times. Considering breakthrough infections have become prevalent and new variants continue to emerge every now and then, the demand for a booster dose is increasing. The administration of a booster shot is expected to re-expose a person’s immune system to the immunizing antigen, the memory of which (following previous doses) could have been lost over a period of time.

Dr. S.N Aravinda, Consultant – Internal Medicine, Aster RV Hospital, JP Nagar, Bengaluru also agrees that vaccine-induced immunity may wane over time. This is why, according to her, “Most vaccines have a certain time period beyond which another shot is required in order to reactivate the immune system to produce antibodies, providing protection against a particular disease.”

He further highlights the fact that all existing COVID-19 vaccines have been recently developed and each vaccine has been made distinctly. “Depending on clinical trials and findings, vaccines that are producing antibodies for a duration of 8 months to a year may only require booster shots every few months to keep the immunity going,” he says.
