The institute's Dr Ewan Harrison thinks XBB.1.5 probably emerged when someone got infected with two different Omicron types: "A bit of the genome from one virus gets joined up with another bit from a second virus, and they merge, and that goes on to transmit.". Viruses constantly change through mutation. The vaccines have always had to contend with variants: The Alpha variant (also known as B.1.1.7) was already spreading around the world when the first COVID-19 vaccination campaigns began.
