Does the Pfizer / BioNTech vaccine neutralize the Brazilian covid strain?


Does the Pfizer / BioNTech vaccine neutralize the Brazilian covid strain? The COVID-19 vaccine from Pfizer Inc and BioNTech SE has succeeded in neutralizing a new variant of the rapid spread of coronavirus in Brazil,

according to a laboratory study published Monday in the New England Journal of Medicine.

Blood taken from people who were given the vaccine neutralized a technical version of the virus that contained the same mutations carried on the tip of the highly contagious variant P.1 first identified in Brazil.

The scientists said the neutralizing ability was roughly equivalent to the effect of the vaccine on a less contagious earlier version of the virus last year.

Moreover, previously, Pfizer stated that the serum

The product has proven its ability to neutralize the British version of COVID-19, as well as the South African strain of the virus. However, the South African strain can reduce the protective antibodies triggered by the anti-COVID serum, informs Reuters.

Pfizer said its current vaccine is very likely to continue to protect against the South African strain. However, the researchers intend to test the third booster dose of the vaccine, as well as a reorganized version specifically to combat the strain, to better understand the immune response.

The Brazilian strain has arrived

in Romania too

On Monday, the National Institute of Public Health – National Center for Surveillance and Control of Communicable Diseases announced the first two cases of infection with the Brazilian strain in Romania. According to INSP data, one of the cases is a 38-year-old man from Bucharest. The patient is symptomatic, with pre-existing medical conditions and no history of travel.

The second case is also a 57-year-old man, also from Bucharest, aged 57. The patient is symptomatic, with pre-existing medical conditions,

but which would come from an outbreak of infection with three cases.

In this context, Raed Arafat stated on Antena 3 that the only truly effective solution is vaccination, and the most important precaution is to comply with all health regulations.

“It was to be expected (…) If you travel, if people go on vacation everywhere, it was clear that we will end up with these strains in Romania. The only method of control remains the protection part: mask, spacing, certain measures to limit the spread, as ordered in Timisoara.

I took action for what I was

criticized: the negative tests performed in the last 72 hours on boarding the planes coming from the countries in the yellow zones to Romania.

The vaccine remains the optimal solution. It is possible to reach other booster doses, just like in the case of the flu vaccine, because there are mutations that require new doses, ”said the head of DSU, at the Meeting Point.
