The Israeli prime minister, Naftali Bennett, has received a third shot of the Pfizer/BioNTech’s Covid-19 vaccine after Israel extended its booster campaign for people over 40 to try to curb the Delta coronavirus variant.
Cases in Israel have surged since Delta’s emergence and Bennett, 49, has sought to avoid an economically painful national lockdown by ramping up third doses.
People over 60 began receiving third doses in July, before the minimum age of eligibility was dropped to 50, with health ministry officials citing waning immunity from earlier vaccinations and Delta’s high infectiousness.
The health ministry said on Friday boosters would be administered to people over 40 whose second shot was at least five months ago. It recommended teachers, health workers, carers of elderly people, and pregnant women of all ages have the shot.
The US has announced plans to offer booster shots to all Americans, citing data showing diminishing protection. Canada, France and Germany have also announced booster campaigns.
“If you go get vaccinated with a third shot we will be able to avoid a fourth lockdown,” Bennett said on Friday before receiving his booster shot live on social media. He said Israel would share its data.
More than 1 million of Israel’s 9.3 million population has received a third shot, which an Israeli healthcare provider said on Wednesday was 86% effective in preventing infection. Health officials have said they are seeing initial signs that the booster campaign may be slowing the rate at which cases are climbing.
About 1 million eligible Israelis have not had the vaccine and severe cases have been climbing, although few fully vaccinated 40- to 50-year-olds have fallen seriously ill.
Studies have shown the vaccine is highly effective in preventing serious illness but its effectiveness against new infections fell as the Delta variant spread. There is no consensus among scientists and health agencies that a third dose is necessary.
The World Health Organization said on Wednesday current data did not indicate a need for boosters and that the most vulnerable people worldwide should be fully vaccinated before high-income countries deploy a top-up.
Pfizer has said its vaccine’s efficacy drops over time and that a third dose showed significantly higher neutralising antibodies against the initial Sars-CoV-2 virus and the Beta and Delta variants.
