A group of researchers at Qatar analyzed814 734 Recipients of Pfizer and Modern Vaccines By using two national cohort studies to compare the effectiveness of vaccines among those with and without COVID infection before vaccination. The researchers examined the impact of revolutionary infections among the beneficiaries of each vaccine and compared the number among those who had COVID before vaccination and those who did not have. And what they found is that the recipients of the Pfizer vaccine that had gévid before their blows are much less likely to catch the virus again.

According to the conclusions - which have been published on Medrxiv on July 26, but have not yet been examined by peers - those who had obtainedInfected by COVID before obtaining the anti-Pfizer vaccine were more protected against the virus, especially alpha and beta variants, which were dominant during the study period. The anti-Pfizer vaccine reduced the rate of COVID breakthrough infection from those previously taken from the 85% virus compared to the beneficiaries of Pfizer without prior infection.

"Among the people vaccinated with [Pfizer], the protection against the infection has been further strengthened and the incidence of infections has been further reduced by an earlier infection," the researchers said in the study.

However, there was no marked difference in the number of revolutionary cases among those who had the modern vaccine, which they had the virus before or not. "On the other hand, people vaccinated with [Moderna] were as well protected as those who received the vaccine after an earlier infection," the researchers said.

The authors note that the incidence rates of breakthrough infection of the two vaccines were low, despite Qatar knowing Covid surges between January and June 2021 due to alpha and beta variants. Researchers say it shows that the two vaccines are effective in protecting beneficiaries who had COVID before vaccination and those who did not.

The results of the new study are similar to an April report financed by the National Institute of Health (NIH) in the United States, which found that a single dose of thePfizer vaccine produces antibody levels Among those who had recovered from a Covid infection similar to the levels found in people without prior infection after two doses of vaccine.

The authors of Qatar history concluded that their conclusions "could have implications for the potential need for a reminder vaccination". But if some experts have considered that some experts have delayed second blows for those who have already had Covid as a result of research like this, disease control and prevention centers (CDC) still recommends individuals.Get the two shots In a two-dose series according to the standard chronology, even if they had previously Covid.

"You should get a Covid-19 vaccine, which you already had Covid-19," said the CDC. "It's because experts do not know how much time you are protected from getting sick after recovering from COVID-19. Studies have shown that vaccination offers a sharp increase in protection in people who have ended up COVID-19. "
