A booster shot of Pfizer’s COVID-19 vaccine significantly improved protection from infection for older adults in Israel, a new study showed.
The third shot offered people ages 60 and older four times as much protection after 10 days than those who only received two doses, according to findings from the country’s Health Ministry on Sunday.
The booster also provided five to six times stronger protection against hospitalization or serious illness after 10 days in the same age group.
The findings were in line with a separate study from Israel’s Maccabi healthcare provider, one of several organizations administering the shots to curb case surges in the country caused by the highly contagious Delta variant.
Around 1.5 million of the country’s 9.3 million residents have received a third jab.
Israel launched a campaign last month to administer third doses to those ages 60 and older, as well as immunocompromised people.
Last week, the country changed the eligibility to include people over the age of 40, pregnant women, teachers and healthcare workers.
The decision to go ahead with the booster shots comes after studies showed that immunity from vaccines had diminished over time.
The US has also begun to administer third doses to immunocompromised people and announced plans to give booster shots to more Americans.
