Two doses of AstraZeneca COVID-19 vaccine 85-90 per cent effective: Public Health England

London, May 21 

Two doses of the Oxford/AstraZeneca COVID-19 vaccine are around 85 per cent to 90 per cent effective against symptomatic disease, Public Health England (PHE) has said, citing a new analysis of real-world data from the rollout of the shot in the UK.

In its latest weekly COVID-19 vaccine surveillance report on Thursday, the PHE also estimated that 13,000 deaths have now been prevented in people aged 60 years or older in England up to May 9, 2021 (11,100 deaths in individuals aged 80 years and older, 1,600 in individuals aged 70 to 79 and 300 in individuals aged 60 to 69 years).

New analysis for the first time estimates that 2 doses of the Oxford/AstraZeneca vaccine provide around 85 to 90 per cent protection against symptomatic disease, PHE said in a press release.

That compares to 90 per cent estimated effectiveness against symptomatic disease for the Pfizer/BioNTech vaccine, according to reports.

Commenting on the PHE data, UK Health and Social Care Secretary, Matt Hancock said the new statistics show the vaccine "saves lives and protects you from ending up in hospital with COVID-19."

"The 13,000 deaths and the 39,100 hospitalisations that have been prevented are not just numbers. They are our family, our friends, our loved ones and a poignant reminder of the impact the vaccine is having," he said.

With the threat of new variants, it has never been more important to get the vaccine, Hancock added.

UK's Vaccines Minister, Nadhim Zahawi said: "This new data highlights the incredible impact that both doses of the vaccine can have, with a second dose of the Oxford/AstraZeneca vaccine providing up to 90 per cent protection."

"There is no better weapon to send this virus into retreat than our life-saving vaccines. A second dose is vital to ensure you have the strongest possible protection so we can return to normality and get back to the things we love," Zahawi said.

PHE estimates also indicate that the vaccination programme has prevented around 39,100 hospitalisations in those aged 65 years and over in England (approximately 4,700 admissions in those aged 65 to 74, 15,400 in those aged 75 to 84 and 19,000 in those aged 85 and over).

The method for analysing the approximate number of deaths and hospitalisations prevented by the vaccine programme now takes into account the impact of both first and second doses, due to more data being available. 

Previously, the method only used the impact of the first dose of vaccination on hospitalisations and deaths. PTI
