First identified in India, Delta is becoming the globally dominant version of the coronavirus, according to the World Health Organization.
Alon Rappaport, Pfizer's medical director in Israel, said data accumulating from research and from those places where the Indian variant, Delta, has replaced the British variant as the common variant, point to Pfizer vaccine being very effective, around 90%, in preventing the coronavirus disease.
An analysis by Public Health England, where the Delta variant is more widespread, found that both the Pfizer/BioNTech and AstraZeneca vaccines provide more than 90% protection against hospitalization from the Delta variant.
