The
coronavirus vaccine candidate being developed by AstraZeneca and
Oxford University induces a strong immune response and appears to be safe, according to preliminary trial results.
The early stage trial, which involved 1,077 people, has found that the vaccine trains the immune system to produce antibodies and white blood cells capable of fighting the virus. It also causes few side effects.
Professor Sarah Gilbert, co-author of the Oxford University study, described the findings as promising but said there “is still much work to be done before we can confirm if our vaccine will help manage the
Covid-19 pandemic”.
Prime minister
Boris Johnson said the results were ”very positive” as he congratulated the team of scientists working on the vaccine.
“There are no guarantees, we’re not there yet & further trials will be necessary – but this is an important step in the right direction,” he said on Twitter.
