“I think many of us working in infectious disease realized that after the first couple of surges, it wouldn’t just go away completely, because that’s not what viruses like this do,” Dr. Shruti Gohil, associate medical director of epidemiology and infection prevention at the University of California, Irvine, told Live Science. … And because SARS-CoV-2 (the virus that causes COVID-19) can mutate into more infectious and/or immune-evading variants, as omicron has clearly shown, we will probably need to update vaccine formulations, Gohil said.
Will we need more COVID-19 boosters to end the pandemic?
