AstraZeneca's COVID-19 vaccine produces an immune response in elderly people, the drugmaker said on Monday.
This does not necessarily mean the vaccine, being developed alongside the University of Oxford, is safe and effective in older people — but it is promising news, given that the immune system weakens as a person grows older.AstraZeneca also said "reactogenicity" — expected adverse reactions to the virus, which commonly include sore arm or swelling — was lower in older people than younger people.
"The results further build the body of evidence for the safety and immunogenicity of AZD1222," the name of the vaccine, the spokesperson added.The drugmakers' statement Monday came after the the Financial Times reported that the vaccine, one of the world's leading candidates, triggers protective antibodies and T-cells in older people, citing two people familiar with trial data.
The findings came from blood tests carried out on a subset of older participants in the
With dozens of vaccine candidates in late-stage clinical trials, including AstraZeneca's, hope remains that a safe, effective vaccine will be developed before the end of the year.White House coronavirus advisor Dr. Anthony Fauci said in a BBC interview on Sunday: "We will know whether a vaccine is safe and effective by the end of November, the beginning of December."
Fauci added: "The question is: Once you have a safe and effective vaccine, or more than one, how can you get it to the people who need it as quickly as possible?"
