Could this be why the flu shots didn’t work? Multiple strains of the virus.The variants are here but aren't yet the dominant strain.
The one growing the fastest in the US is the UK B117 variant that has shown to 90% more contagious than the standard variant with SOME ability to avoid neutralizing antibodies from a previous infection. Fortunately, both Pfizer and Moderna seem to lose no effectiveness to this variant.
There is a more worrisome variant B135 from South Africa that is similarly contagious but pretty much avoids all protection from previous infection. The oxford vaccine has no effect on it. Moderna and Pfizer are likely less effective, but we dont know for sure yet.
B117 will become the dominant strain in the US likely in April, however I wouldn't expect nearly the spike because of protection from both the vaccine and previous infection/herd immunity.
B135 is not as certain...its here in the US and has been detected in Texas, Florida, and New York.
so if there end up being 1000 strains of this virus, would you suggest we get 1000 vaccines?
