Scientists want to understand why SARS-CoV-2 variants identified in the United Kingdom and South Africa seem to be spreading so quickly, and whether they might diminish the potency of vaccines or overcome natural immunity and lead to spate of reinfections. > “Many of us are scrambling to make sense of the new variants, and the million-dollar question is what significance this will have for the effectiveness of vaccines that are currently being administered,” says Jeremy Luban, a virologist at the University of Massachusetts Medical School in Worcester.
