It is “very unlikely” that the vaccines currently available will not be effective on the reported new variant of Covid-19 in the United Kingdom, Operation Warp Speed head Moncef Slaoui told CNN on Sunday.
“Up to now, I don’t think there has been a single variant that would be resistant to the vaccine,” Slaoui said. “We can’t exclude it, but it’s not there now.”
Slaoui said that Covid-19 may be prone to variance, as the RNA process the virus uses is more prone to mistakes. He added that critical aspects of the virus, like the spike protein involved in a vaccine, are very specific to Covid-19 and unlikely to mutate much.
“Because the vaccines are using antibodies against many different parts of the spike protein, the chances that all of them change, I think, are low,” said Slaoui.
