Did you get sick in Corona and get vaccinated?

The chances of you getting infected again are very low

A new study examining the effectiveness of vaccines against re-infection among recovering patients found that a vaccine given to people aged 16-64 reduces the possibility of re-infection by 82%.

The study also shows that no benefit was found for administering two vaccines to recoverers, over giving one vaccine.

"This is significant information"

A vaccine given to recoverers from Corona aged 16-64 was found to reduce the possibility of re-infection with the virus by 82%, according to a new study that examined the effectiveness of vaccines against re-infection in the recovering group.

It was also found that among people aged 65 and over who recovered and were vaccinated for the first time, the vaccine reduces the possibility of re-infection by 60%.

The risk of contracting the corona virus is significantly reduced among corona recoverers, but it has not yet been known how long this protection survives.

Following this, the Ministry of Health recommended that corona recoverers who have not yet been vaccinated be vaccinated in one dose three months after their recovery.

The study by Clalit Health Fund, published tonight in the leading medical journal New England Journal of Medicine, followed all Clalit patients aged 16 and over who recovered from Corona and at least three months had passed since their recovery.

The study compared the rates of re-infection in Corona in the population that received one or more doses of vaccine after recovery, compared with the rates of re-infection among recovering patients who were not vaccinated at all.

Until now it was not known how long the defense lasted.

The follow-up was carried out between March 1, 2021 - the date on which the Ministry of Health approved the vaccination of recovering people from Corona until November 26, 2021 - towards the end of the delta wave in Israel.

The researchers reviewed data from 149,032 patients in the fund who had recovered from corona disease.

The study also shows that no benefit was found for administering two vaccines to recoverers over giving one vaccine.

This finding supports the guidelines of the Ministry of Health in Israel to be satisfied with one vaccine for recovering people.

In addition, the study does not indicate whether there is an effect on the time span from recovery to vaccination and re-infection.

The head of Clalit Health Fund's community medicine department, Dr. Doron Netzer, stressed the importance of the results of the study. Because after recovery from corona antibodies are formed in the body, but due to the lack of evidence-based information for a period of time of this protection - it was recommended that vaccines be given to recoverers as well.

"This is the first significant study that shows that corona recoverers also benefit from this vaccine," Netzer said.

"The early recommendation to vaccinate recoverers helped curb the Delta Wave."

"The results of our study show unequivocally that giving corona vaccine to recoverers is significantly associated with reducing the risk of re-infection," he added.

"It is clear beyond any doubt that the Ministry of Health's recommendation as early as March 2021 to vaccinate recoverers has been very helpful in curbing the delta wave for all its implications. "I wore masks than in the younger population. Therefore, the relative increase in protection from the vaccine is less, but still very significant."
