Over 10,000 Israelis test positive within two weeks of receiving the first dose, while antibody tests on health workers show ‘the vaccine works wonderfully’ after the second dose
Over 12,400 Israeli residents have tested positive for COVID-19 after being vaccinated, among them 69 people who had already gotten the second dose, which began to be administered early last week, the Health Ministry reported.
This amounts to 6.6 percent of the 189,000 vaccinated people who took coronavirus tests after being vaccinated.
According to the ministry’s data, 5,348 people were found infected up to a week after getting the vaccine, of the 100,000 people who were vaccinated and then tested a week later – an infection rate of 5.4 percent of those vaccinated during that time.
Another 5,585 people tested positive for the virus between the eighth and 14th day after getting the first vaccine – 8.3 percent of the 67,000 people who were vaccinated and tested during that post-vaccination period.
People were also testing positive more than two weeks after getting the first dose, between the 15th and 21st day, a period during which partial immunity is already meant to be in effect. Of the 20,000 people tested during this post-vaccine period, 1,410 people tested positive, some 7.2 percent. Of the 3,199 people who took coronavirus tests between day 22 and day 28 after the first vaccine, 84 were found to be positive (2.6 percent), including 69 people who had already been vaccinated twice.
Some 2.15 million people have been vaccinated in Israel over the past month, of whom 300,000 have already gotten a second dose.
At this stage it is still difficult to draw definitive conclusions about the effectiveness of the vaccine, for better or worse. In some groups of inoculated people during the different post-vaccine periods, the ratio of positive tests corresponds to the ratio of positive tests in the general population, the overwhelming majority of whom were not yet vaccinated.
There could also be issues related to the fact that most of those vaccinated first and who have thus accumulated the most post-vaccination time are over 60 years old.

Meanwhile, serological tests done on employees of Sheba Medical Center at Tel Hashomer a week after they had received the second dose of the Pfizer vaccine showed that of 102 employees tested, 100 had antibody levels between 6 to 20 times higher than they had presented a week earlier.
