Mr Alon Rappaport, Pfizer's medical director in Israel, told local broadcaster Army Radio: "The data we have today, accumulating from research we are conducting at the lab and including data from those places where the Indian variant, Delta, has replaced the British variant as the common variant, point to our vaccine being very effective, around 90 per cent, in preventing the coronavirus disease, Covid-19."
