BCG vaccination beneficial against Covid infection for elderly: ICMR study

New Delhi: Indian Council of Medical Research (ICMR) has said that Bacillus CalmetteGuérin (BCG) vaccination can be beneficial for elderly individuals in tackling novel coronavirus infection.

As per a study conducted by ICMR, BCG vaccination induces enhanced innate and adaptive immunity innate in elderly individuals and ‘may prove beneficial against Covid-19’.

‘In an ongoing study, scientists at the council have found that the vaccine induces increased memory cell responses and total antibody production in elderly,’ ICMR tweeted.

According to researchers, BCG vaccination was associated with enhanced innate and adaptive memory cell subsets, as well as total antibody levels in elderly individuals, suggesting its potential utility in SARS-Cov2 infection by enhancing heterologous immunity.
