We do know that this is a variant that has a lot of mutations – like 50 そのうちの, 以上 30 of those in the spike protein, which is the part off the virus that attaches to your human cells if you get infected,” コリンズは言った. “That is a new record in terms of the number of mutations. It does make you worry, したがって、, that it’s a sufficiently different virus, that it might not respond as well to protection from the vaccines. But we don’t know that.

Collins added that the swift spread of the variant would indicate that it is highly contagious, but it remains unclear how severe it is.

Collins said it will taketwo or three weeksto tell whether antibodies from vaccines or previous infections will be effective against omicron.

Despite the lack of knowledge regarding protection, しかしながら, Collins encouraged people who have not been vaccinated or received boosters yet to get those shots. Collins stated that the existing shots have proven to be effective against different variants, and that boosters in particular have worked against different spike proteins.

It’s clear that in all the previous examples of variants, the vaccines have worked to provide protection and the boosters have provided especially strong protection against things like delta,” コリンズは言った. “Given that history, we expect that most likely the current vaccines will be sufficient to provide protection and especially the boosters will give that additional layer of protection.

If it turns out that a new vaccine is needed to combat omicron, Pfizer and Moderna are already working on one, コリンズは言った. He noted, しかしながら, that this would take at least two or three months.

Collins also addressed the travel restrictions that the Biden administration has placed on South Africa due to the omicron variant’s presence there. He called ita difficult decision,” but said given the severity of the variantit made senseto do this, at least on a temporary basis.
