On Monday, AstraZeneca said that the COVID-19 vaccine being developed by the University of Oxford produces a similar immune response in both older and younger adults, and adverse responses were lower among the elderly.
An AstraZeneca spokesman told Reuters: “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.”
“The results further build the body of evidence for the safety and immunogenicity of AZD1222,” the spokesman said, referring to the technical name of the vaccine.
The Oxford/AstraZeneca vaccine is expected to be one of the first from big pharma to secure regulatory approval, along with Pfizer and BioNTech’s candidate.
Immunogenicity blood tests carried out on a subset of older participants echo data released in July which showed the vaccine generated “robust immune responses” in a group of healthy adults aged between 18 and 55, the Financial Times reported.
