Antibodies produced in response SARS-CoV-2 infection They last between six and twelve months after infection, they protect against different types of transmission, and they are even improved. Vaccines.
An international team of scientists led by American Michael Nusensweek, head of the Molecular Immunology Laboratory at Rockefeller University and an investigator at the Howard Hughes Medical Institute, verified this and published the results in the journal “Nature”.
Researchers have found that antibodies continue to develop over a period of 6 to 12 months and improve when an infected person is vaccinated, which is why they conclude that the immune system is immune. COVID-19 It may be durable.
Michael Nusensweek and his colleagues examined blood samples from 63 people COVID-19 In the previous year.
Of these, 26 had already received at least one dose of Moderna or Pfizer-Bioendech vaccines, and found that the range of antibodies produced after 6 to 12 months increased in both purpose and potency.
Later, when individuals were vaccinated, they began to develop antibodies “Very effective” Against different types that already spread SARS-CoV-2.
One year after infection, neutralization of activity against all types of viruses included in this study was less common among non-vaccinated individuals.
This, according to research results, suggests that the vaccine boosts immunity in those already infected.
Researchers also say that cats need to be included in any precautionary measures against the virus. “Reinforcement” Planned in an appropriate way, it can develop a protective immunity against the variants of the virus that spreads around the world.
