Pfizer vaccine protection against S. African variant reduced by two-thirds

Pfizer-BioNTech announced on Wednesday that a study shows the antibody protection of its COVID-19 vaccine may be reduced by two-thirds against the South African variant of the coronavirus. In the study published in the New England Journal of Medicine, scientists from the drug companies and the University of Texas Medical Branch replicated the variant and tested it against blood taken from people who had been given the Pfizer vaccine. They found the level of neutralizing antibodies was two-thirds the level produced in tests using the most common version of COVID-19.  Notice the word VARIANT that you folks said was not important earlier. Enjoy your reading gang.  Cheers

It is here in USA already

A new report published in the New England Journal of Medicine on Wednesday suggests that Pfizer-BioNTech's Covid-19 vaccine can protect people against concerning new coronavirus variants, including one first seen in South Africa called B.1.351.

For the study, researchers at Pfizer and the University of Texas Medical Branch genetically engineered versions of the virus to carry some of the mutations found in B.1.351. They tested them against blood samples taken from 15 people who had received two doses of the Pfizer/BioNTech vaccine as part of a clinical trial. 

While the blood serum samples produced less neutralizing antibody activity, it was still enough to neutralize the virus, they wrote in a letter to the journal. This is in line with other studies. And it's well within what is seen with other viruses, one of the researchers said.

UT Medical Branch Full Letter to the New England Journal of Medicine.   Notice it is a small sample, but still enough to provide protection.  And because mutations always occur, we will be getting booster shots next year to increase immunity.

Ah those of you that cling to wishful thinking and say a dog is a cat and a cat is a dog are very amazing.  Cheers

I no longer read the comments of certain biased members replying to my topics.  It is easy to skip over these cats.
