Pfizer vaccine 'works' against key variant mutation

focuses on a mutation called N501Y, which as emerged in both new variants.

This is thought to be important because it is in the part of the virus that makes first contact with our body's cells and changes could make it easier to get in and cause an infection.The researchers created two forms of the virus - one with and one without the mutation - and then bathed those viruses in blood samples taken from 20 patients that had been vaccinated in clinical trials.

"The mutation selected is only one of eight in the UK variant, and in fact was not expected to have significant impact alone," Prof Ravi Gupta, from the University of Cambridge said. Prof Stephen Evans, from the London School of Hygiene & Tropical Medicine, said: "Had the opposite result been found... that would have been bad and very concerning.

"So, yes this is good news, but it does not yet give us total confidence that the Pfizer vaccines will definitely give protection."

Can I ask for clarity, Is this after one or two doses? I’ve read in the bmj_latest that Virologists suggest half vaccinating can give the virus a chance to mutate to be vaccine resistant?

How much is Pfizer paying you in adverts?

And how long have they been testing this

What's up with the apostrophes ? Are you indicating that the vaccine is not effective? How is the general public to understand this?

“So, yes this is good news, but it does not yet give us total confidence that the Pfizer (or other) vaccines will definitely give protection.” The final sentence in this article - doesn’t really equate to ‘works’ does it?
