Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said the two approved vaccines, one by Pfizer and BioNTech and another by Moderna, both have enough of a cushion to protect against these two strains of the virus. Still, scientists expect the coronavirus to continue to mutate.
The CDC and NIH are working with drug and vaccine makers to develop what they call boosts that would use the same platform as the vaccines and incorporate immunogenS that combat the new strains. To successfully do that, scientists need to stay a step or two ahead of the virus’s trajectory.
States are currently collecting virus strains, and scientists are conducting genomic surveillance of the virus’s impact on the antibodies produced by the approved vaccines and vaccines currently under review.
But congressional aid would provide more resources to detect new strains of the virus. The coronavirus relief package that lawmakers are debating would include money to step up the sequencing effort and help scientists detect new strains when they first start to emerge, Walensky said.
Thus far, the U.K. variant has shown a very slight impact on vaccine-induced antibodies but nothing else, Fauci said, so that is not enough to diminish the vaccine’s effectiveness.
