The findings of the study, which was conducted by Israel’s largest HMO, the Clalit Health Fund, were based on the testing of 200,000 members of the public aged 60 and above who received the first of two required doses of the vaccine, and an equal number of the same population who did not, Israeli business site Globes reported on Wednesday.

The research showed that between the fifth and 12th days after vaccination, there was no difference in the number of positive coronavirus tests between the two groups. However, from the 14th day onwards the number of positive results in the vaccinated group dropped by 33 percent, while the unvaccinated group’s results remained the same.

The report noted that these findings are in line with Pfizer’s own research, which indicates that the effect of the first dose begins to show after 11 days—strengthening the conclusion that the vaccine, not other factors, is responsible for the variation between the inoculated and non-inoculated groups.

The conclusion is similar to that of Gili Regev, director of Sheba Medical Center at Tel HaShomer’s Infectious Disease Epidemiology Unit. Regev found that while only 1 percent of the 200 people examined who had received the first dose of the vaccine had developed enough antibodies after a week to provide immunity, the number rose to 50 percent after two weeks.

As JNS reported earlier this week, Israeli Prime Minister Benjamin Netanyahu and Health Minister Yuli Edelstein were on hand at Ben-Gurion International Airport on Sunday for the arrival of another shipment of the Pfizer vaccine.

The delivery came a week after Netanyahu’s announcing “Operation Back to Life”—an agreement with Pfizer whereby, in exchange for the company’s pushing forward the date of the arrival of its second batch of vaccines and increasing the amount delivered, Israel will provide the company with statistical data about the country’s inoculation program.

Israeli Health Minister Yuli Edelstein reported on Jan. 10 that Israel has so far administered the first dose of the vaccine to 1,817,000 Israelis and plans to have 5 million fully inoculated by April.
