AIIMS Expert on Covid-19 Booster: Who Should Take It Now?

With new Covid-19 cases reemerging in some parts of the country—most presenting mild symptoms—questions are surfacing once again about the need for Covid-19 booster doses. The world is well aware of the devastation caused by this pandemic since its initial outbreak in December 2019. As new cases reappear, public anxiety has begun to grow.

In this context, Dr. Ranjan, a senior professor at the All India Institute of Medical Sciences (AIIMS), stated that booster doses of the Covid-19 vaccine play a critical role in preventing infections among the elderly and those suffering from chronic illnesses.

Dr. Ranjan emphasized that booster doses designed to target Omicron-related variants are particularly important in reducing hospital admissions, severe disease, and mortality. However, he also pointed out that these booster doses may be less effective in preventing infections that present with mild or no symptoms.

He noted that while immediate need for booster doses may not be urgent for everyone, individuals who have not received a booster in over a year should consider taking one to enhance waning immunity. “Updated monovalent vaccines targeting strains like JN.1 or those close to it are expected to provide protection against severe illness caused by variants such as LF.7 and NB.1.8,” Dr. Ranjan explained.

Reports from Southeast Asian countries and China indicate a rise in new infections due to Omicron sub-variants. Dr. Ranjan, analyzing the recent Covid-19 trends in Singapore, observed that while new cases have risen, ICU admissions have slightly decreased, and most infections are not severe.

Regarding India, Dr. Ranjan observed that the situation remains stable. As of mid-May, the number of infections nationwide has remained low. He noted that the recent rise in cases is limited to a few states and even in those areas, most infections have been mild, with individuals recovering without the need for hospitalization.

Dr. Ranjan urged the public not to panic, but to stay informed about mild symptoms and be prepared. “Awareness about mild symptoms, the benefits of vaccination, and the importance of protecting vulnerable groups should be emphasized. Reliable channels should be used to combat misinformation,” he advised.
