A British study confirms high efficacy of BioNTech/Pfizer and AstraZeneca vaccines against the Delta variant of coronavirus.
Two doses of the Covid-19 vaccine from BioNTech/Pfizer or AstraZeneca are almost as effective against the highly transmissible delta variant of the coronavirus as against the previously dominant alpha variant, according to the study published in the New England Journal of Medicine.
According to the study, two vaccinations with BioNTech/Pfizer are 88 percent effective in preventing symptomatic disease from the delta variant, compared with 93.7 percent against the alpha variant. Dual vaccination with AstraZeneca is 67 percent effective in protecting against the delta variant, compared with 74.5 percent against the alpha variant.
