Sumary of Inactivated virus vaccine Covaxin has cellular immune memory to Covid for at least 6 months: NII:
- New Delhi, November 15 The inactivated virus vaccine Covaxin has immunological memory to SARS-CoV-2 and its variants of concern for at least up to six months, National Institute of Immunology director in-charge Pushkar Sharma said, implying the vaccine can provide protection for a minimum of that duration.
- Immunological memory is the ability of the immune system to respond more rapidly and effectively to pathogens that have been encountered previously.
- Sharma presented the work done by the institution in understanding fundamental processes that regulate inflammation, pathogenesis, ageing and immune response, the Science and Technology Ministry said in a statement.
- He mentioned that significant efforts have been made towards transitional research specifically for SARS-CoV-2 vaccine.
- He further mentioned that the inactivated virus vaccine BBV152/Covaxin elicits robust cellular immune memory to SARS-CoV-2 and variants of concern—Delta, Alpha, Beta and Gamma—which persist at least up to six months.
