Israel hopes boosters can avert new lockdown as Covid vaccine efficacy fades Earliest to vaccinate, Israel is the first country to confront fading protection of Pfizer’s jabs with a third shot

By August, according to the health ministry, studies showed the Pfizer vaccine’s efficacy against infection falling to 39 per cent, and to as low as 16 per cent for people who had their second shots in January. Most worryingly, the vaccine’s efficacy for the prevention of severe disease in the most vulnerable cohort — Israelis aged over 65, most of whom were double-jabbed by January — had dropped to 55 per cent, the ministry said. Immunologists and experts, both in Israel and outside, have questioned the precision of that data, which the Israeli government released quietly and without any clarity on its methodology.

Other international studies have also shown lower efficacy for the Pfizer vaccine against the Delta variant and waning immunity over time, but the estimated declines have generally been smaller. An Oxford university study published on Thursday found that the efficacy of the Pfizer vaccine against symptomatic infection almost halved after four months. Pfizer, which has worked closely with Israel during the pandemic and is pushing for the use of boosters globally, supported the government’s assessment. “These latest data from Israel are consistent with the epidemiological trends we have been observing and reinforce the need for a booster dose to re-establish maximum protective efficacy,” Pfizer said in response to questions.
