According to the New York Post, AFP and the guardian, the injection speed of new crown vaccine in Israel is the fastest in the world. As of the 22nd, about 2.5 million people with a population of 9 million have been vaccinated with the first dose of vaccine jointly developed by Pfizer of the United States and biontech of Germany. On the 23rd, the country began to include people aged 16 to 18 into the scope of vaccination, becoming the first country in the world to vaccinate teenagers. However, the controversy over the efficacy of Pfizer’s first dose vaccine continues. The Joint Commission on vaccination and immunization (JCVI) of the United Kingdom even points out that according to the preliminary data of a small study in China, the protective effect of Pfizer’s first dose vaccine may be as low as 33%.

The novel coronavirus pneumonia in Israel is still grim, with 4933 new diagnoses confirmed on 23. The authorities decided to extend the nationwide blockade period from 19 to 31 this month, and to include teenagers in the vaccination program. Israel’s Ministry of Health announced on the 21st that teenagers aged 16 to 18 can be vaccinated with the new crown vaccine with the permission of their parents.

Clalit, the country’s largest medical service provider, began vaccinating teenagers on the 23rd. Israeli Prime Minister Benjamin Netanyahu said all citizens over the age of 16 would be vaccinated by the end of March. “Education must be our top priority. After we make sure that teachers are vaccinated, we must make sure that young people can take exams and go back to school as soon as possible,” said Israeli Deputy Prime Minister and defense minister Ganz. ”

Admitting that the utility is not as good as expected

Israel started its vaccination program on December 19 last year. As of December 22, about 2.5 million people had received the first dose of the vaccine jointly developed by Pfizer of the United States and biontech of Germany, and 900000 of them had received the second dose. However, the health department pointed out that 189000 people received the new crown test after vaccination, of which 12400 were positive, and 69 were still diagnosed after the second dose.

As early as before Israel’s cabinet meeting on the 19th discussed whether to expand the nationwide City closure, chief epidemic prevention expert Ashe questioned the efficiency of Pfizer’s first dose of vaccine. He pointed out that many people were diagnosed after the first dose of the vaccine, which showed that the effect after the first dose of the vaccine was “lower than we expected” and the effective rate was not as high as 52% as Pfizer said. The Ministry of health immediately explained that Ashe’s remarks were not accurate.

But health minister Edelstein changed his mouth on the 24th, admitting that the first dose of vaccine could not immediately prevent new coronavirus infection. He said he was very sorry to see someone infected with the virus after the first dose of the vaccine, but at the same time, after the first dose of the vaccine, the number of critically ill patients and hospitalized patients decreased. He also said that the vaccine is not a panacea, we have to coexist with the new coronavirus for a long time.

Who: vaccine does not cause death in frail elderly

Anthony Harnden, vice-chairman of the Joint Commission on vaccination and immunization (JCVI), said they were looking at preliminary data from a small Israeli study that showed that after the first dose of Pfizer vaccine, the protection might be as low as 33%. But he stressed that this is only preliminary data and further research is needed.

Previously, a study in Israel invited 200000 people over the age of 60 who had received the first dose of Pfizer vaccine to compare with the control group who had not been vaccinated and had a similar age. The research team found that the effective rate of the vaccine was only 33% 14 days after vaccination.

In addition, in the face of the controversy over the possible death of Pfizer vaccine, the WHO Global Advisory Committee said on the 22nd that there was no evidence that Pfizer vaccine caused the death of frail elders, and that the vaccination was still beneficial to the elderly.

Hahndon also said that people may eventually need to be vaccinated once a year to keep up with the changes in the virus. But he believes that the public should be assured that these technologies are relatively easy to edit and adjust, and that once they find a new dominant strain, the vaccine can be adjusted accordingly.
