LONDON - One of the world's leading COVID-19 experimental vaccines produces a immune response in both old and young adults.
The vaccine, developed by the University of Oxford, also triggers lower adverse responses among the elderly, British drug maker AstraZeneca Plc, which is helping manufacture the vaccine, said on Monday.
"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.
AstraZeneca did not provide detail of the data behind the statement or say when it would publish eagerly awaited late-stage phase III trial data, which would show whether the vaccine works well enough in large scale trials for it to be approved.
