In the weeks ahead, we will learn more about how well the antibodies induced by the current vaccinations can neutralize the omicron variant in the laboratory. Lots of people have built up some immunity from past infections and vaccination, which is helping to make the . The World Health Organization (WHO) confirmed that XBB.1.5 has a "growth advantage" over other sub-variants seen so far.
