Israeli study found that Pfizer vaccine is less effective in spreading Delta mutations


A study released by the Israeli Ministry of Health shows that the BioNTech/Pfizer vaccine is not as effective as previous coronavirus strains in preventing the spread of Delta variants.

The Ministry of Health found that data collected in the past month showed that the vaccine was 64% effective in preventing infection in fully vaccinated people. It is estimated to be 94% effective against previous virus strains.

However, the data originally reported on the Ynet news portal indicated that the vaccine is 93% effective against severe diseases and hospitalization.

Since Israel lifted all remaining Covid-19 restrictions on June 1, the number of cases has continued to increase, and many experts have blamed the highly spread variant of Delta.

As of Monday, the country had nearly 2,600 active cases, more than double the number of the previous week, but the Ministry of Health said only 35 cases were considered serious.

Earlier this year, the British health authorities also recorded Decreased efficacy The Pfizer jab is not as serious as the Delta variant. Public Health England found in May that the vaccine provided 88% protection against symptomatic Delta infections and 93% protection against Alpha variants first discovered in Kent. According to the study, two doses of the Oxford/AstraZeneca vaccine have a lower protection of the Delta variant at 66%.

After lifting the blockade in the spring, Israel enjoyed one of the fastest vaccination events in the world. Of Israel’s 9 million citizens, more than 5 million have been fully vaccinated.

The rising case rate shocked the Naftali Bennett government. The government re-implemented mask requirements for indoor gatherings and public transportation last month, and is considering more restrictive measures, including the reintroduction of the “green passport” program for people who have been vaccinated, restrictions on large public gatherings, and “strengthening” injections.

Last week, young people, including the prime minister’s daughter, were vaccinated, and more than 100,000 people received the injection.
