Israel: Pfizer vaccine efficacy, 39% prevention of infection, 91% prevention of severe disease
[아시아경제 김유리 기자] In Israel, the government recently announced that the efficacy of Pfizer’s vaccine to prevent COVID-19 infection has fallen sharply again.
According to local media on the 23rd (local time), the Israeli Ministry of Health announced the day before that the efficacy of Pfizer vaccine’s prevention of COVID-19 infection had dropped to 39%. The Ministry of Health said, however, that the vaccine’s efficacy in severe prevention was maintained at 91%, and prevention efficacy in hospitalization was maintained at 88%.
The Ministry of Health said that among the 1,152,914 cases of COVID-19 tested in the past month, 5,770 cases, which are estimated to have developed immunity after receiving two doses of the vaccine, were so-called ‘breakthrough infections’. Of the breakthrough cases, 495 were hospitalized, of which 334 were classified as critically ill and 123 died.
This is lower than the preventive efficacy announced by the Israeli Ministry of Health two weeks ago. At that time, the Ministry of Health said that after the spread of the delta mutation, the efficacy of the Pfizer vaccine in preventing infection was reduced to 64% and the efficacy in preventing severe infection was reduced to 93%.
Israel started public vaccination on December 19, last year, when Pfizer’s vaccine was initially distributed, and so far, 5.75 million people, or 62% of the total population of about 9.3 million, have completed the first dose. About 5.28 million people, or 57%, completed the second vaccination.
In response, Israel lifted most quarantine measures early last month and lifted the obligation to wear a mask indoors in the middle of the same month. However, as the number of daily confirmed cases surged again as the delta mutation spread, some quarantine measures were restored, such as wearing a mask indoors. Recently, the number of daily confirmed cases has risen to the level of 1300-1400.
