Blood tests carried out on a set of older participants reflect a data released in July, which showed the Covid vaccine did generate “robust immune responses” in healthy adults aged 18 to 55.
AstraZeneca Plc said it was encouraging to see immune response in both younger and older adults.
“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,” an AstraZeneca spokesman said.
“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.
As the world tries to plot a path out of the Covid-19 pandemic, the Oxford/AstraZeneca vaccine is expected to be one of the first from big pharma to secure regulatory approval, along with Pfizer PFE.N and BioNTech’s 22UAy.F candidate.
It if works, a vaccine would help the world return to some type of normalcy.
