Spike protein vaccines may help fight Covid variants: IIT-M study

Researchers sought to gauge the response in cases where post-vaccination infections were caused by a variant other than the original Wuhan strain

While further experimental verification is called for, the researchers believe that the present spike protein vaccines are likely to be efficacious against circulating variants of Coronavirus

Spike protein vaccines may be effective against multiple variants of the coronavirus (SARS COV-2), according to a study by researchers at Indian Institute of Technology Madras (IIT Madras). The spike protein is one of the four major proteins found in coronaviruses; it helps the Sars-CoV-2 virus to latch on to a host cell and, in turn, infect the body eventually.

The results of the study suggest that the threat from the selected variants — Delta plus, Gamma, Zeta, Mink and Omicron — may be dealt with by vaccine-induced T cell responses in spite of having compromised neutralising antibodies. T cells are
