What we know about the Epsilon variant of coronavirus: Can evade vaccine protection, common treatments and more | The Times of India


Experts suggest that specific mutations in the Epsilon variant including three in the spike protein help the virus to dodge the protection given by the COVID vaccines or past Covid-19 infection.

According to researchers from University of Washington and the San Francisco-based lab Vir Biotechnology, Epsilon variant has three spike protein mutations which helps it to weaken current vaccines by up to 70%. Scientists noted that the three mutations in the Epsilon coronavirus spike protein reduced the effectiveness of the antibodies in someone’s bloodstream, generated either by vaccines or past COVID infections.

After testing the resilience of blood plasma from vaccinated people and those who had already had COVID, researchers found that the ability to neutralise the Epsilon variant was reduced to 2 and 3.5 times.
