Oxford-AstraZeneca COVID-19 vaccine

Explore the timeline of our research to help develop the Oxford-AstraZeneca COVID-19 vaccine and its impact.

Published: 28 October 2022

Reducing transmission and saving lives

The NIHR and its partners played a critical role in the successful development and roll-out of a safe vaccine to combat the COVID-19 pandemic.

Our research has shown that the Oxford AstraZeneca COVID-19 vaccine is safe and effective at preventing COVID-19 infection and transmission, with a single dose offering good protection.

More than 37 million people in the UK received this vaccine or another approved vaccine, thanks to NIHR support.

Research

An estimated 10,400 deaths in over 60s in England are prevented during the first three months of the vaccination programme.

A single dose of the vaccine is shown to reduce transmission of infection to others by 65%, and reduce household transmission from symptomatic cases by up to half.

The data and sequence of events presented in the infographic is a snapshot of the wider work carried out across the research and development and health and care research ecosystem in the UK. It was not possible to undertake a comprehensive analysis of all the work that has underpinned this area.

This infographic should therefore be treated as a high-level overview.
