This is excellent news! Every time that I see a new variant pop up I get pretty nervous that our current shots won't be effective against it. And with the new variant spreading pretty rapidly throughout Brazil, this one made me just as nervous as any. But news just came out that Pfizer's shot has been proven to be effective against the new variant out of Brazil. I would take it that this also means the Moderna shot will be as well, though I'm not sure if the Johnson & Johnson shot will be the same. I believe the three are different in certain ways, but the Moderna and Pfizer shot are similar enough.
Hopefully we can continue to knock out these new variants with our current shots as they appear. As we've seen, these things can rapidly get out of hand if we're not prepared for them. The good thing is we got the first variations of the shot out so fast that now we have something to work with if we need to change it here and there instead of starting from scratch.
That's great. I had a feeling that the shots would be mostly effective against the variants, but it's nice to know they are.
The good thing about the mRNA shots is that they can be easily tinkered with to fight against new variants. I don't think either Moderna or Pfizer have done that with any variant yet, but it is nice to know that they could if they have to.
