The ChAdOx1 nCov-2019 coronavirus vaccine, developed by teams at the University of Oxford, has been shown to trigger a robust immune response in healthy adults aged 56-69 and those over 70 years of age.

Our vaccine work is progressing quickly. To ensure you have the latest information or to find out more about the trial, please visit the Oxford COVID-19 vaccine web hub or visit the COVID-19 trial website.

The data, published today in The Lancetsuggest that one of the groups most vulnerable to serious illness, and death from COVID-19, could build immunity.

Older adults have been shown to be at higher risk from COVID-19 and should be considered to be a priority for immunisation should any effective vaccine be developed for the disease. Reporting on data from a Phase II trial of the ChAdOx1 nCov-2019 vaccine, the authors write that volunteers in the trial demonstrate similar neutralising antibody titres, and T cell responses across all three age groups (18-55, 56-79, and 70+).

During the Phase 2 trial the vaccine has been evaluated in 560 healthy adult volunteers aged between 18-55 years, 56-69 years and aged 70 or over. Volunteers received 2 doses of the vaccine ChAdOx1 nCoV-19, or a placebo MenACWY vaccine. No serious adverse health events related to ChAdOx1 nCoV-19 were seen in these volunteers.
