"There are over 300 subvariants of Omicron. I think the one that is concerning right now is XBB, which is a recombinant virus. We had seen some recombinant viruses earlier. It is very immune-evasive, which means it can overcome the antibodies. So slightly that we may see another wave of infections in some countries because of XBB," WHO said.
