What's Driving the Lady Surge?

Before the lady surge, many people had been infected and even more than a hundred million people had been vaccinated in india. So it was very puzzling to scientists in italy that this massive surge was able to take root. One variant called b one six, one seven, has really spread to many different places where other variants seem be the predominant variant previously. And what that's really suggesting is thata b one six,one seven, is more transmissible, potentially, than some of these other variants,. That's why really it's managing to rapidly spread all over India.
