Pfizer/BioNTech Vaccine Equally Effective for All Age Groups, Israeli Study Says

March 1, 2021

The Pfizer/BioNTech COVID-19 vaccine showed the same effectiveness for all age groups — including individuals over age 60 — confirmed a new study from Israel that included almost 1.2 million individuals.

The vaccine gave 94 percent protection against symptomatic COVID-19 infection after a second shot, said researchers from Israel’s Clalit Research Institute and Harvard University, who published their findings in the New England Journal of Medicine.

The 94 percent effectiveness is close to the 95 percent efficacy reported from Pfizer’s global phase 3 study of 43,000 participants, but it provides critical real-world data, especially on older patients.
