Current Covid vaccines may protect from disease caused by Omicron: Study

Current COVID-19 vaccines prompt the body to make effective, long-lasting T cells against SARS-CoV-2 that can recognise variants of concern, including Omicron, and protect from severe disease, a study has found. The research, published in the journal Cell, also shows that fully vaccinated people have fewer memory B cells and neutralising antibodies against the Omicron variant. Both T and B cells play an important role in the immune response against an infection. Scientists at La Jolla Institute for Immunology (LJI) in the US tested four COVID-19 vaccines -- Pfizer-BioNTech, Moderna, J&J/Janssen, and Novavax. "The vast majority of T cell responses are still effective against Omicron," said study co-leader Alessandro Sette, a professor at LJI. "These cells won't stop you from getting infected, but in many cases they are likely to keep you from getting very ill," said co-author Shane Crotty, a professor at LJI. This is true in all the type of vaccines studied, and up to six months .
