LONDON (Reuters) - British Prime Minister Boris Johnson described early stage clinical trial data on an AstraZeneca COVID-19 vaccine as very positive on Monday.
“This is very positive news. A huge well done to our brilliant, world-leading scientists & researchers at @UniofOxford,” Johnson said, on Twitter, linking to a report on the data.
“There are no guarantees, we’re not there yet & further trials will be necessary - but this is an important step in the right direction.”
