Chennai: The Indian Institute of Technology Madras (IIT-M) researchers have shown that spike protein vaccines may be effective
against multiple variants of the Coronavirus (SARS COV-2).
The results of the IIT-M study suggest that the attack by selected variants --Delta plus, Gamma, Zeta, Mink and Omicron--may be dealt with by vaccine induced T-cell responses despite the compromised neutralising antibodies responses.
