A new study claims that antibodies will improve on our body during post Covid infection.
Another recent study has shown that 99 percent of people who tested for SARS-CoV-2 preserved antibodies to the Coronavirus for three months after getting infected.
A New Study States Antibodies Last for a Longer Time During Post COVID Infection
How long immunity will last to the novel Coronavirus? The recent Rockefeller study offers motivating answers and also recommends that people who recover from Coronavirus are protected against the SARS-CoV-2 for almost six months or longer.
The study was published in Nature, submitted the strongest evidence that the immune system learns the virus and excellently continues to improve the quality of antibodies even after the virus no longer exists in the body. Antibodies produced in the body months after the infection showed mounted ability to fight SARS-CoV-2, and also its mutated versions including the South African variant.
The study discovered that these improved antibodies are developed by immune cells that are kept on evolving, due to continued exposure to the remnants of the Coronavirus kept hidden in the gut tissue.
Research also stated that patients who recover from the virus, again exposed to the same virus in that case antibody’s response will be faster and more effective and also help prevent re-infection.
Michel C. Nussenzweig, the Zanvil A. Cohn, and Ralph M. Steinman Professor and head of the Laboratory of Molecular Immunology stated “This is really exciting news. The type of immune response we see here could potentially provide protection for quite some time, by enabling the body to mount a rapid and effective response to the virus upon re-exposure.” whose team also observed and characterized antibody response in Coronavirus patients since the beginning of the pandemic in New York.
Antibodies are Produced in Post Covid Infection
Scientists from UK Biobank discovered that 87.8% remained seropositive for six months. The study also stated that antibodies produced based on the natural infection provides a certain amount of protection for most people.
Sir Patrick Vallance, the Government’s chief scientific adviser stated the results of the study as “useful confirmation of the maintenance of antibodies”.
The recent studies also stated that COVID-19 provided at least 83% protection against reinfection during (post Covid infection) compared with people who had not to get infected before.
Naomi Allen, the chief scientist for UK Biobank and professor of epidemiology at the University of Oxford, described briefly in the Science Media Centre: “When you take our findings that antibody levels seem to persist for at least 6 months, together with findings from other studies that show that the likelihood of reinfection following a natural infection is fairly low over the same period of time, it does suggest that people may be protected against subsequent infection for at least 6 months following a first infection with the virus.”
Researchers stated important questions remained. Professor Sir Rory Collins, UK Biobank principal investigator stated “We can’t be sure that this provides a complete protection.”
The professor of medicine and epidemiology at the University of Oxford, Sir Rory added, “and we still don’t know either with the vaccines or indeed with people who have been infected, whether they can still be transmitters and put others at risk.”
Researchers said they haven’t got any chance to assess antibody levels during the time in people who had received the COVID-19 vaccine compared to those people who were infected naturally.
Sir Rory told the press that, “Whether the punch is bigger or smaller I’m not sure, but you clearly get a very good punch with both.”
Researchers described they were not able to explain antibody persistence from new variants of the SARS-CoV-2 virus because these viruses were not affecting a large number of people during their research.
England’s health minister Lord Bethell stated “While the findings offer some promise, now is not the time for complacency. We still do not fully understand how long protection from antibodies may last, and we know people with antibodies may still be able to pass the virus on to others.”
“Right now, it remains vital for everyone to stay at home, even if you have had COVID-19 in the past, so we can stop the spread of the virus, protect the NHS and save lives.”
