Israeli Prime Minister: Pfizer vaccine anti-Delta weaker than expected

The rapid mass vaccination against pneumonia in Wuhan has put daily life back on track, while Israel, which has been hailed as a “model student of epidemic prevention,” has recently seen the epidemic rise again under the invasion of the Delta variant of the virus. Japanese media “COURRIER JAPAN” reported on the 19th, the Israeli Prime Minister Bennett (Naftali Bennett) has recently indicated in a cabinet meeting, the United States Pfizer (Pfizer) and Germany BioNTech biotechnology companies to cooperate in the development of the Wu lung vaccine, against Delta virus is “weaker than originally thought”.

Prior to this, the Israeli Ministry of Health noted in early July that the effectiveness of the Pfizer/BNT vaccine against the Delta variant was reduced to 64%, but protection against severe illness and hospitalization remained at 93%. More than 5 million of Israel’s 9.3 million people have received two doses of the Pfizer vaccine, and 60% of the population has received at least one dose. The number of new cases per day dropped dramatically from more than 10,000 in January to a single-digit number in June, but the epidemic has resumed after the lifting of restrictions due to the aggressive onset of the Delta variant.

Israel recently confirmed more than half of the new cases of Delta infection after vaccination

According to Johns Hopkins University, as of the evening of the 19th of Taiwan time, Israel has administered nearly 109.8 million doses of vaccine; nearly 523.5 million people have been vaccinated. Fifty-five thousand people, accounting for 58% of the total population. Since the outbreak, there have been more than 850,000 confirmed cases and more than 640,000 deaths in Israel. There were 755 confirmed cases and three new deaths on the 18th, and nearly 560 confirmed cases and 11 new deaths in the past week. More than half of the recently diagnosed patients were vaccinated but still infected with the Delta variant. Up to 60 percent of the newly diagnosed patients with severe disease had received the vaccine.

According to The Times of Israel, Bennett said at an outbreak assessment meeting that the vaccine provides “less protection than we expected” against the Delta virus and that the vaccine alone is not enough to stop the outbreak. While Bennett affirmed that the vaccine is indeed effective against the virus, it is unclear “how far the vaccine can help”; the vaccine is significantly less effective against the Delta virus than other previous variants of the virus.

Israel cancels 3rd dose for patients with compromised immune systems

At the same time, Israel also canceled the recently announced third dose of vaccination part of the policy, that is, the third dose of Pfizer/BNT vaccine for patients with compromised immune systems, including people who have received heart, lung and kidney transplants and some cancer patients, said that after reviewing the data of patients in oncology wards, it was found that nearly 90% of patients receiving chemotherapy developed antibodies after receiving two doses of vaccine, and the antibodies remained high after several months. The vaccination may also produce side effects that may affect tumor treatment, so it is recommended at this stage that cancer patients not receive a third dose of the vaccine.
