Researchers at the Indian Institute of Technology Madras have shown that spike protein vaccines may be effective against several variants of SARS-CoV-2.
The study suggests that despite compromised neutralising antibodies, vaccine-induced T cell responses could deal with variants such as Delta Plus, Gamma, Zeta, Mink and Omicron. The researchers have called for more experimental verification of their findings.
The team studied the response to post-vaccination infections by variants other than the original Wuhan strain incorporated in the vaccine. Vaccination is a process through which a part of or a milder form of the virus is introduced into the body. Pieces of a protein, called epitopes, of the injected virus/viral part trigger an immune response in the body.
