Israeli, UK data offer mixed signals on vaccine’s potency against Delta strain

Unread post by uncledad »

Local research claims Pfizer shot now only 41% effective against symptomatic COVID, while British stats have it at 88%

Israel’s research agreed, at least, that the shot was highly effective in avoiding serious illness, at 91.4% effectiveness.

Some analysts have warned that the figures on vaccine effectiveness are prone to major inaccuracies because of a range of factors, including questions over whether there is accurate data on infection levels among the non-vaccinated, which is vital for such stats.

Reacting to the Israeli figures on Thursday, epidemiologist Nadav Davidovitch, a Ben-Gurion University professor and leader of Israel’s doctors’ union, told The Times of Israel, “What we see is that the vaccine is less effective in preventing transmission, but it’s easy to overlook that it’s still very effective in preventing hospitalization and severe cases.” ... ta-strain/

The bigger picture...

Davidovitch added: “It’s still excellent, very good in preventing severe cases and death, but less so in preventing transmission. And this is why we can’t rely on vaccinations alone, but also need Green Passes, testing, masks, and the like.”

The renewed restrictions will apply to both indoor and outdoor events with over 100 participants, starting on July 29. The requirement to present proof of vaccination, recovery or a negative test from the past 72 hours will only apply to people older than 12. Under that age, there will be no restrictions.
