University of Oxford , 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. The data, published today in The Lancet, suggest that one of the groups most vulnerable to serious illness, and death from COVID-19, could build immunity.
British pharmaceutical giant AstraZeneca, which is working in collaboration with the University of Oxford, has previously said interim data showed their experimental vaccine had produced an immune response in older and younger adults.
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+).
