Triple mutation in SARS-CoV-2 seen in second wave of COVID-19 in India
Researchers sequenced the viral genome from samples in the state of Maharashtra and found a unique combination of three mutations that suggest the SARS-CoV-2 virus is continually evolving to evade the human immune response.
With the COVID-19 pandemic continuing to spread in several parts of the world, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is evolving to evade our immune system. Several new variants, designated variants of concern, have been reported from the United Kingdom, South Africa, and Brazil at the end of 2020, which seem to be more infectious than the original strain.
COVID second wave: Mutant variants driving rise in high-burden states
On the strains, such as the double and triple mutant detected in India, they said all are the same variant of the virus, and the available vaccines are effective on them.

NEW DELHI: Experts engaged in genome analysis say that one of the reasons behind the surge in the Covid-19 cases could be increasing mutant variants in many cities, especially in high-burden states.
Ask Derrick
We ask our science correspondent Derrick Williams whether new variants of the coronavirus mean that we will need to develop new vaccines.
