Chennai: One of Britain’s largest studies of its kind has said that getting two vaccine doses remains the most effective way to ensure protection against the Covid-19 Delta variant of concern (VOC).
The study by scientists at the University of Oxford involved over 700,000 randomly selected people from within the community.
It claimed that the Pfizer/BioNTech and Oxford/AstraZeneca vaccines still offer good protection against new infections. The Oxford/AstraZeneca vaccine is being produced and administered in India as Covishield.
With Delta, Pfizer/BioNTech and Oxford/AstraZeneca vaccines still offer good protection against new infections, but effectiveness is reduced compared with Alpha (first identified in England last year and previously the dominant VOC in the UK), according to the findings released by the university’s Nuffield Department of Medicine.
