Prime Minister Benjamin Netanyahu on Saturday became the first person to be vaccinated in Israel. Opinion polls show some two-thirds of the public want to follow suit.

The Justice Ministry said that, at its request, Facebook took down four groups at the weekend that had disseminated texts, photographs and videos with "deliberately mendacious content designed to mislead about coronavirus vaccines".

Such "fake news" included arguments that vaccines would be used to plant government tracking chips in recipients' bodies, to poison them and thus cull the population or to subject them to medical experimentation, the ministry said in a statement.

A Facebook spokeswoman confirmed that four Hebrew-language groups had been taken down as part of the company's policy against "spreading misinformation regarding the vaccines".

Israeli officials say the country has enough vaccines on order by year's end to protect the most vulnerable 20% of the population and then lift some coronavirus curbs, but worry that turnout might be dampened if people get false information about the innoculations.

Israel began administering vaccines to medical staff on Sunday. At Tel Aviv Sourasky Medical Center, dozens of doctors and nurses danced as they prepared to receive their injections.

Next in line are elderly Israelis or those in high-risk groups. The wider adult population is slated to get shots in early 2021.

With a population of 9 million, Israel has logged 373,368 coronavirus cases and 3,074 deaths. It has imposed two national lockdowns and is mulling new curbs on high-contagion areas.
