Current corona vaccine may be less effective against beta variant of corona, claims study


Boston [USA]

The current corona vaccine may be less effective against beta variants of the corona virus. This has come to the fore in a recent study. These studies suggest that current vaccines may be less effective against the beta variant first identified in South Africa. The spike proteins on the surface of SARS-COV-2 enable the virus to bind to and enter our cells, and all current vaccines are working against it, the study said.

The study, published in the journal Science on June 24, used cryo-electron microscopy (cryo-EM) to compare the spike protein with a beta variant from the original coronavirus found in China in 2019, and the first identification of an alpha variant. was done. Cryo-M is an imaging technique used to quantify biomolecular structures at near-atomic resolution.

The findings, led by researchers from Boston Children’s Hospital in the US, suggest that a mutation in the beta variant, also known as b.1.351, alters the shape of the spike surface at certain locations. As a result, these neutralizing antibodies made from current vaccines are less able to bind to beta viruses, which may allow people to evade the immune system even if they are vaccinated.
