Pfizer and Moderna are both effective to within the mid-high 90's, was my understanding.

the thing that scares me is that Pfizer is "only" ~75% against B.1.351. I'm not worried right now, and I've relaxed a ton since before, but I'm nervous that B.1.351 and other vaccine-resistant strains will rise to prominence once enough people are vaccinated.

Wait, Pfizer is only ~75% effective against B.1.351? Can you provide a source. I was not aware of that and it's worrisome.

"The effectiveness against any documented infection with the B.1.351 variant was 75.0% (95% CI, 70.5 to 78.9). Vaccine effectiveness against severe, critical, or fatal disease due to infection with any SARS-CoV-2 (with the B.1.1.7 and B.1.351 variants being predominant within Qatar) was very high, at 97.4% (95% CI, 92.2 to 99.5). Sensitivity analyses confirmed these results (Table S3)."

so it's still quite effective at preventing severe illness, which is why I'm not terribly worried, but still spooky that strains are starting to mutate away from our protection.

And so we will synth a new one in a 2 weeks, just like the last one. The important thing is that we have a cold supply distribution chain, readily available production for mRNA synthesis, and emergency authorizations, which will become regular vax authorizations when it is shown to be a new cutting edge technique and a new golden age in fighting viral infections. Go, go ASAP. Get it. It won’t be your last. But it might be the last of viral cancers, covs, hiv…

The US is solving that by not getting enough people vaccinated :/
