Pfizer and AstraZeneca vaccines are both effective against the Delta form, according to research

A study published on Wednesday found that two doses of Pfizer or AstraZeneca’s Covid-19 vaccination are nearly as effective against the highly transmissible Delta coronavirus variant as they are against the previously prevalent Alpha form.

Officials say vaccines are highly effective against the Delta variant, now the dominant variant worldwide, though the study reiterated that one shot of the vaccines is not enough for high protection.The study, published in the New England Journal of Medicine, confirms headline findings given by Public Health England in May about the efficacy of Covid-19 vaccines made by Pfizer-BioNTech and Oxford-AstraZeneca, based on real-world data.

Wednesday’s study found that two doses of Pfizer’s shot was 88% effective at preventing symptomatic disease from the Delta variant, compared to 93.7% against the Alpha variant, broadly the same as previously reported.Two shots of AstraZeneca vaccine were 67% effective against the Delta variant, up from 60% originally reported, and 74.5% effective against the Alpha variant, compared to an original estimate of 66% effectiveness.

“Our finding of reduced effectiveness after the first dose would support efforts to maximise vaccine uptake with two doses among vulnerable groups in the context of circulation of the Delta variant,” the authors of the study said.
