New lab study shows troubling signs that Pfizer's & Moderna's Covid shots could be far less effective against SA strain (arms, symptoms)

Not good news. 10 times less effective would mean 10% or less effective against the newer strain?

• Pfizer's and Moderna's shots were at least 10 times less effective against variant in a new study.
• Researchers tested the vaccines on a variant first found in South Africa, which is now in 20 states.
• A mutation on the variant called E484K appeared to be a "major contributor," the study authors said.

COVID-19 vaccines from Moderna and Pfizer-BioNTech appear significantly less effective against the coronavirus variant first found in South Africa, a lab study has suggested.
The percentage of protective antibodies that neutralized the variant - called B.1.351, which has been recorded in 20 US states - was 12.4 times lower for Moderna's COVID-19 shot than against the original coronavirus, and 10.3 times lower for Pfizer's, the study authors said.

Well, that's bad news and I certainly hate to hear it, but I can't say that I'm surprised. Trying to vaccinate against the many Coronavirus variants is probably about like trying to vaccinate against the common cold. I believe that some treatment or medicine that might help fight or prevent the worst symptoms may be a better and more effective route than trying to develop a vaccine that is effective against something that is mutating so fast.

By the time that we take months (maybe a year or so) to develop a vaccine and then another year to get it into the arms of millions of Americans, the virus has mutated so much that the vaccine is largely ineffective against many of the current strains. Just when many Americans are finally beginning to see the light at the end of the tunnel, we get news that the light is actually the headlight of an oncoming freight train.

That is my worry that we are always one step behind the virus. I am going to get first shot of the vaccine Friday. Figure something is better than nothing. But jabbing people over and over with new updated vaccines or boosters seems a little concerning. We have no idea what that cocktail will do long term. I work from home so I can avoid most human contact. I feel bad for those who have to be out there in the middle of this.
