Will the next variant be more virulent? Answering this Maria Van Kerkhove, WHO’s Covid-19 technical lead, said, the next variant of concern will be more fit, i.e.
it will be more transmissible because it will have to overtake what is currently circulating. However, “The big question is whether or not future variants will be more or less severe." Speaking against theories that the virus will continue to mutate into milder strains, she added, “There is no guarantee of that.
We hope that that is the case, but there is no guarantee of that and we can’t bank on it." The next iteration of Covid may also evade vaccine protections even more, making the existing vaccines even less effective, she pointed out. When will COVID end? This completely depends on us and how we behave.
Noting that COVID is not over yet, Kerkhove said, "You won't have to wear a mask forever and you won't have to physically distance forever.
