The study demonstrates the efficacy of the Pfizer vaccine against the Brazilian version of Kovid-19

According to a new study unveiled on Tuesday, the Pfizer-BioNotech Kovid-19 vaccine appears to be very effective against the more infectious version of the virus first discovered in Brazil.

Neutralization of the Brazilian variant known as p.1 was “approximately equal” to the original strain of the virus against which the Pfizer vaccine was found to be 95% effective, the study published in the “New England Journal of Medicine” said Is “in the United States.

The P.1 variant has spread rapidly to Brazil in early January, with Kovid-19 already affecting people.

According to the US Center for Disease Control and Prevention (CDC), only 15 cases of Brazilian stress have been identified in nine states.

The study also revealed the strong neutrality of the version B.1.1.7, first identified in Britain.

The type B.1.351, first identified in South Africa, is considered the most dangerous, because of its ability to weaken the efficacy of vaccines to some extent. The study showed that neutralization of this variant was “strong but weak”. “We are seeing strong neutral activity against all strains including P1, which is spreading so quickly in Brazil,” Carl Bergstrom, a professor of biology at the University of Washington, said in a tweet. “Although activity has decreased against the B.1.351 strain from South Africa, it is still very influential,” he explains.

The study authors cautioned that their results are based on laboratory analysis and are not yet valid with real-world data. The new study of the vaccine, created by the American company Pfizer and its German partner BioNotech, was done by scientists from both companies and researchers from the medical arm of the University of Texas. This comes as a warning to public health experts that the most variable variant may be further exacerbated in Kovid-19 cases.
