More than a million people in Israel have already been infected and recovered from corona, but many of them choose to avoid getting vaccinated in one dose as usual, as they estimate that they have enough antibodies to prevent further infection.
New research may change their minds.
Several studies have recently shown that at least some of the people infected with SARS-CoV-2 in 2020 and vaccinated with mRNA vaccines like Pfizer or Modern this year have "superhuman" or "hybrid" immunity, meaning they produce very high levels of antibodies capable of neutralizing different versions. Of the corona virus and other viruses.

These people are "Corona Variants Factory"

In one small study from Rockefeller University in New York that has not yet been tested, antibodies from 14 people vaccinated with one vaccine after being infected with corona in the past were able to neutralize six strains of corona virus, including delta and beta, several other related viruses, including the first virus, SARS- CoV-1, first identified in 2003 and drastically different from SARS-CoV-2, the virus that causes corona.
Some people will be resistant to other strains in the future.

These "flexible" antibodies may even neutralize other viruses.
Antibodies from vaccinated people who have not been infected with corona in the past or unvaccinated people who have been infected in the past have meanwhile been "helpless" against some of these viruses.
"It is reasonable to predict that people with hybrid immunity will be fairly protected from the majority, and perhaps all, of the SARS-CoV-2 versions we are likely to see in the foreseeable future," says study editor Paul Bianias, a Rockefeller University virologist.
He suspects they will also have "some degree of protection against SARS-like viruses that have not yet infected humans."

Another study found that healthy people who had been vaccinated in the corona in the past and received one vaccine had 6 to 100 times more antibodies compared to people who had been vaccinated once, twice, or had been infected in the corona in the past and had not been vaccinated.
Another study published in the Telegraph found that up to a third of people with a previous infection do not produce antibodies at all.
On the plus side, a study by the University of Pennsylvania immunologist, John Vary and colleagues, shows that "some of this antibody development occurs in people who have just been vaccinated."
