Two new studies show that immunity to the coronavirus may last for years and can grow stronger after vaccinations, The New York Times reports.
The key findings of the studies suggest that people who have contracted the virus and have been vaccinated will likely not need a booster shot. However, those who have received their jabs but have never tested positive for the virus may still need a booster.
Both studies examined people who had been infected with the coronavirus about a year ago, and one of the studies found that certain cells will store the genetic information of the virus in bone marrow until it is needed to fight against infection.
The other study, which is still under review, suggests that the aforementioned memory B cells grow stronger for at least another 12 months after initial infection.
Let’s get to the point, making the research simpler for you:
Important immune cells survive in the bone marrow of people who were infected with the virus or were inoculated against it, suggests the new research.
The results of Dr. Nussenzweig’s study suggest that those who recovered from Covid-19 and got vaccinated later on vaccinated will continue to have extremely high levels of protection against emerging variants, even without receiving a vaccine booster down the line.
It’s a sign to get your jab as soon as possible.
The team of researchers had enrolled 77 participants who gave blood samples at three-month intervals starting about a month after initial infection. Most of the participants had mild cases of covid-19; only six, out of all, were hospitalized so far.
Immunity to the coronavirus can last for a year at least, possibly can last a lifetime, improving over time especially after vaccination, according to two new studies. The findings may help put to rest lingering fears that protection against the virus will be short-lived.
However those who are vaccinated and never infected most likely will need the shots.
*However, as will a minority who were infected but did not produce a robust immune response.
Published earlier in the week in the Journal Nature ,the findings suggest that mild cases of covid-19 leave those infected with lasting antibody protection and that repeated bouts of illness are likely to be uncommon.
The researchers found antibody producing cells in people 11 months after first symptoms. These cells will live and produce antibodies for the rest of people’s lives. That’s strong evidence for long-lasting immunity,” said senior author Ali Ellebedy, PhD, an associate professor of pathology and immunology, of medicine and of molecular microbiology.
Those who recovered from Covid now have good news. Instead of hearing about all the ill effects after recovery , they may develop antibodies that can last a lifetime.
