Health authorities emphasised that the two-dose Pfizer vaccination protocol ensures that the vaccine is entirely effective for around five weeks after the first dose.
Any 21 residents of the Bat Yam retirement home tested positive for coronavirus after they had been vaccinated but had developed antibodies, according to Ynet.
The remaining 150 inhabitants of the home will be screened for the infection.
Health authorities emphasised that the two-dose Pfizer vaccination protocol ensures that the vaccine is entirely effective for around five weeks after the first dose. This suggests that enough elderly and high-risk individuals will be vaccinated by some time in February to help reduce the spread of illness and start re-opening the economy.
On Friday morning, in the presence of Prime Minister Benjamin Netanyahu and Health Minister Yuli Edelstein, one millionth Israeli resident was vaccinated against the novel coronavirus.
Israel is the world’s number one per capita when it comes to vaccines. Any 10% of the population has already earned the first jab.
However, the epidemic has not stopped spreading, and health authorities are preparing to call on the government to increase controls next week, possibly shutting the way Israel has done over Yom Kippur.
