The Pfizer COVID vaccine is 70 percent effective against the new ultra-contagious Delta variant, claims a new study from the Hebrew University, according to Kan. This is compared to an approximately 95% rate of effectivity of the vaccine against earlier strains of COVID.

According to the study, the Pfizer-BioNTech vaccine is also less effective at preventing people infected with the Delta variant from developing serious symptoms.

Earlier today, Haaretz reports on Health Ministry figures that indicated that the Delta variant is responsible for more than 90% of new COVID cases in Israel over the past two weeks; compared to just 60% of new cases in the country just two weeks ago.
