Study shows U.K. COVID variant unlikely to “escape” Pfizer vaccine

Real-time studies are underway to monitor the efficacy of Pfizer’s vaccine, and the others certified for use in the U.S. New coronavirus mutations raise concerns


They tested 16 blood samples from people who had both shots of the Pfizer vaccine against their synthetic U.K. The latest lab results come after similar positive findings from a study carried out by Pfizer and the University of Texas that were published earlier this month. strain. First published on January 20, 2021 / 7:38 AM variant, along with a replica they created of the original strain from Wuhan, China, and found “no biologically significant difference in neutralization activity.”

It doesn’t amount yet to definitive proof that the Pfizer vaccine will have the same 95% efficacy against the British strain as it did against the original virus in large-scale human trials. variant] spike would be neutralized efficiently” by the Pfizer/BioNTech vaccine. variant — the N501Y mutation, which is also seen in a strain from South Africa — would not make the new versions of the bug resistant to its vaccine.But as the scientists noted in the study published this week, “the question remained whether a virus with the full set of mutations in the lineage B.1.1.7 [U.K. and around the world.

While outside researchers have yet to verify their findings, it does provide more hope that the variant — thought to be at least 50% easier to pass from an infected person to a new human host — can be controlled with the vaccine, which is already widely used in the U.S. and South African variants, and initial data could come within a couple weeks.But with the U.K. coronavirus death toll surpasses 400,000

New research published on Tuesday by Pfizer and its German partner BioNTech provides further evidence that their COVID-19 vaccine should be effective against the highly-infectious coronavirus variant first detected in the U.K. 

The study published Tuesday on the website, which hasn’t yet been peer-reviewed, relies laboratory testing of a small number of blood samples from people inoculated with the Pfizer vaccine against a synthetic version of the new virus strain.A look at global trust in COVID-19 vaccinesWhile only 16 blood samples were tested, the study’s authors, including BioNTech’s two co-founders, said the new data on the antibodies produced by their vaccine, combined with other immunity-inducing factors of the drug, “make it unlikely that the B.1.1.7 lineage [U.K. and Europe, against the U.K. variant fueling mounting concern in the U.S., Europe and around the world, given how fast it spreads and that it’s already popped up in about 60 countries, it is more reason to hope that the weapons already developed to turn the tide in the pandemic will remain useful. Study provides more evidence that U.K. Pfizer called those initial results “a very reassuring finding” that one particular change in the U.K. COVID variant won’t “escape” Pfizer’s vaccine
