Could New SARS-CoV-2 Variants Undermine COVID Vaccines?
Researchers race to determine why variants that emerged in UK and in Africa spread so rapidly, and whether they will impact vaccine efficacy
As concern grows over faster-spreading variants of coronavirus, labs worldwide are racing to unpick the biology of these viruses. 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.
