Taking a third dose of the Pfizer COVID-19 vaccine boosts the immunity of recipients more than tenfold compared to those who received only two doses of the vaccine more than five prior, according to a report published by Israeli researchers in the New England Journal of Medicine.

A version of the study had been previously published and reported on, though not peer-reviewed, at the beginning of the month on the online research hub MedRxiv.

The Health Ministry’s Epidemiological division and its coronavirus vaccine advisory committee convened Tuesday for a repeat discussion of the vaccination of individuals who recovered from the coronavirus and green pass restrictions for unvaccinated individuals who recovered from the virus following the publication of new ministry data on the subject.

According to the data, those who received a third dose of the coronavirus vaccine have 10 times the protection of those who were vaccinated with two doses between January and March. In addition, those who recovered from the virus and received just one dose of the vaccine have similar protection to those who received the third dose and were twice to three times as protected as those who recovered from the virus but were not inoculated against the disease.

So far, 6,054,298 Israelis have received at least one dose of the coronavirus vaccine, while 5,563,259 have received two doses. Nearly 3 million – 2,966,594 – have received all three available doses of the vaccine.
