Only one dose of Pfizer-BioNtech’s Corona vaccine is effective on those who have been infected with Corona. The latest study claimed this. According to the researchers, a single dose produces a strong immunity against corona in such people. It does not matter when they were infected or whether they contained antibodies during the infection.

Researchers at Bar-Ilan University and Jive Medical Center in Israel said that there is still little evidence in the world regarding corona vaccines. He said that the effect of the vaccine in people who have been cured of corona is not yet fully understood.

The latest study, published in the journal Euroservillance, involved a group of 514 personnel at Jive Medical Center. 17 participants were infected with corona at some time between one and 10 months before taking the first dose of the vaccine.

Antibody levels of the entire group were measured prior to vaccination and after that the Pfizer vaccine effect was observed. Researchers said the vaccine’s effect was quite effective in those who had previously been infected by the epidemic. This triggered discussion regarding whether a single dose of the vaccine may be sufficient.
