, though it likely still offered some protection.
To prevent the evolution of even more dangerous variants, it's crucial to wear a mask, avoid indoor crowds, wash hands frequently and get vaccinated when possible, Fauci said at a White House briefing earlier in the week. All five of the vaccines which the U.S. government has contracted to buy, target the"spike" protein on the surface of the SARS-CoV-2 virus. Mutations to that protein in the South African variant are believed to be behind the reduced vaccine effectiveness.
Some might be able to evade vaccines, treatments and diagnostics, but won't spread enough in the U.S. to pose a problem here.It's not exactly clear how long it would take to make a vaccine that addresses a new variant, or several, because it's never been done before. "This flexibility includes the ability to alter the RNA sequence in the vaccine to cover new strains of the virus," the statement reads."If one ever were to emerge that is not well covered by the current vaccine, the updated vaccine could be administered as a booster."
Viruses mutate. That is why they have to tweak the flu vaccine every year. That is why there is no vaccine for the common cold. The coronavirus is a cousin to these. The Pfizer CEO may know this, that is why he sold Pfizer stock when their vaccine was announced.
