A third dose of the Pfizer COVID-19 vaccine seems to be effective 86% of the time, according to Israeli health officials.

  • An Israeli health care provider said Wednesday that the initial results of a study of thousands of members of the health care system Israeli HMO Maccabi showed the vaccine was 86% effective in people aged over 60 years old, per Reuters.

The study reviewed data of 149,144 people who were older than 60 who received a third Pfizer dose at least one week ago compared to those who had only received two doses between January and February.

  • Thirty-seven people tested positive for COVID-19 after their third jab, compared to the 1,064 positive cases from those who tested positive after their first two doses, according to Reuters.
  • The health officials did not reveal if these cases came from patients who had underlying health conditions, according to Reuters.

The new Israeli data comes on the same day that U.S. health officials said they would call on all Americans to get COVID-19 booster shots, just like what’s happening in Israel now.

  • “We are starting to see evidence of reduced protection against mild and moderate disease,” officials told The New York Times.

Health officials have been monitoring Israel data to see how the delta variant has spread and how immunity from COVID-19 vaccines changes over time, as I wrote for the Deseret News.

Israel has been considered a template for the United States when it comes to COVID-19 vaccinations since the country uses Pfizer — a popular vaccine in the U.S. — and has been rolling out the vaccine pretty rapidly.

  • About 78% of Israel’s population has been vaccinated against COVID-19.

However, Israel has expressed concern that the COVID-19 vaccine does not fully stop the delta variant, as I wrote for the Deseret News. Though it may halt cases and slow them down, it doesn’t fully stop them from happening.
