The Pfizer-BioNTech >PFE.N< vaccine is highly effective against the Delta variant of COVID-19, a Pfizer official in Israel said on Thursday.
First identified in India, Delta is becoming the globally dominant variant of the coronavirus, according to the World Health Organization.
“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%, in preventing the coronavirus disease, COVID-19,” Alon Rappaport, Pfizer’s medical director in Israel, told local broadcaster Army Radio.
A study by researchers from the University of Texas together with Pfizer and BioNtech and published this month by Nature journal found that antibodies elicited by the vaccine were still able to neutralize all tested variants, including Delta, albeit at reduced strength.
