Updated Covid Vaccines Not Urgently Needed With Mild Surge: Former CSIR-IGIB Chief To News18
Last Updated:
There's no need to panic, said Anurag Agrawal, as Covid-19, in its current form, is expected to stay mild for the majority
Updated Covid vaccines may not be necessary at this stage, especially in a country like India, where the younger population is less vulnerable to severe outcomes, Anurag Agrawal, former director of the Institute of Genomics and Integrative Biology (IGIB), told News18.
IGIB is a national laboratory of the Council of Scientific & Industrial Research (CSIR).
India is witnessing a Covid-19 surge, with a total of 1,010 active cases as of May 26, 2025. The highest number of active cases is in Kerala (430), followed by Maharashtra (210), Delhi (104), and Gujarat (83).
'The current rise in cases can be attributed to waning antibody levels and minor mutations in the virus's spike protein," said Agrawal.
Globally, Agrawal believes the newly updated Covid-19 vaccines are not proving highly effective against emerging strains. 'While mRNA technology allows for rapid updates to match circulating variants, it remains the only platform capable of such flexibility. Other vaccine technologies take much longer to develop and distribute; by the time they are ready, the infection wave often begins to fade," said Agrawal, who is presently dean of the Trivedi School of Biosciences at Ashoka University.

Even with mRNA, he said, there is ongoing debate about its use, hinting towards concerns ranging from long-term safety data to accessibility.
'India is currently seeing cases of the JN.1 strain. However, with a relatively younger demographic and a lower risk of severe disease, there is doubt among experts whether updating vaccines for this specific strain is worthwhile," he said.
According to Agrawal, who is also head of the Koita Centre for Digital Health at Ashoka University, many people may be silent carriers of the virus, showing no symptoms. Additionally, actual case numbers could be much higher than reported, as fewer people are opting for Covid-19 testing.
Despite this, he maintains that no drastic measures are required beyond surveillance and preparedness.
'The susceptibility to severe illness remains low. For those who are highly vulnerable, such as the elderly or immunocompromised, simple precautions remain the best line of defence," said Agrawal, who is a well-known physician-scientist. 'In short, the message is clear: there's no need to panic. Covid-19, in its current form, is expected to stay mild for the majority. A calm, precautionary approach is all that is needed."
