Oxford coronavirus vaccine produces immune response in both young and old: AstraZeneca

Coronavirus vaccine developed by the University of Oxford produces an immune response in both young and old adults, raising hopes of a path out of the destruction caused to life and wealth.

The experimental vaccine also triggers lower adverse responses among the elderly, British drug maker AstraZeneca Plc, which is helping manufacture the vaccine, said on Monday.

A vaccine that works is seen as a game-changer in the battle against the novel coronavirus, which has killed more than 1.15 million people, shuttered swathes of the global economy and turned normal life upside down for billions of people.




“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.

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, as the world tries to plot a path out of the COVID-19 pandemic.



The news that older people get an immune response from the vaccine is positive because the immune system weakens with age and older people are those most at risk of dying from the virus.

If it works, a vaccine would allow the world to return to some measure of normality.
