Most people think they have significant amounts of antibodies five months after illness.
Does he become immune to corona after illness and for how long does he become immune?
This question is one of the most important that exists at the moment, since it can be decisive in determining whether natural herd immunity can be developed and for how long a vaccine will be effective.

Has reached the opposite result
Research in the field so far has yielded mixed results, but according to new research from Mount Sinai Hospital in New York, reproduced in the renowned journal Science, there is nothing to worry about.
– Although there have been reports that antibodies to corona disappear quickly, we have found the exact opposite: More than 90 percent of patients with mild or moderate disease produce an antibody response strong enough to neutralize the virus, and the Response persists for several months, says Florian Krammer, a professor of vaccination at the Icahn School of Medicine at Mount Sinai.

– Finding how robust the antibody response to SARS-CoV-2 is, including how long the antibodies remain and the ability to neutralize the virus, is vitally important in order to monitor how many people have antibodies in the population. This is essential for the development of an effective vaccine, he says.
He has studied more than 30,000 people
The study analyzed blood samples from 30,082 people who were tested at Mount Sinei in New York between March and October. The test they have used has revealed not only if there are antibodies in the blood, but also in what amounts.
The researchers’ conclusions are as follows:
– For the vast majority who have mild to moderate symptoms, an antibody response is established that is relatively stable for at least five months, according to Mount Sinai.
There is a decrease in the number of antibodies over time, but they report that most have moderate amounts of antibodies five months after illness.
What happens after that you don’t know yet, because you don’t have secure data. The spread of the infection did not begin in earnest until March.
The New York Times has written extensively before about why a drop in antibody counts over time is not alarming. According to experts in the field, a decrease in the amount of antibodies is a sign of a healthy immune system:
– This does not mean that people no longer have antibodies. That doesn’t mean they aren’t protected, says immunologist Scott Hensley of the University of Pennsylvania.
