Oxford COVID Vaccine Prompts Immune Response in Old & Young Adults

Such results are reassuring since immunity tends to weaken with age, even as older adults are at high risk of death.

The Oxford-AstraZeneca vaccine has been found to produce a similar immune response in older and younger adults, and is associated with lower adverse reactions among the elderly, AstraZeneca said on Monday, 26 October.

According to a Reuters report, a spokesperson from the British drug-maker company stated, “It is encouraging to see immunogenicity responses were similar between older and younger adults and that reactogenicity was lower in older adults, where the COVID-19 disease severity is higher.”
