New Health Ministry statistics indicated that, on average, the Pfizer shot — the vaccine given to nearly all Israelis — is now just 39% effective against infection, while being only 41% effective in preventing symptomatic COVID. Previously, the Pfizer-BioNTech vaccine was well over 90% effective against infection.
Meanwhile, a new UK study published this week in The New England Journal of Medicine found the same vaccine to be 88% effective in preventing symptomatic COVID — more than twice the rate found in the Israeli data.
Israel’s research agreed, at least, that the shot was highly effective in avoiding serious illness, at 91.4% effectiveness.
