Human trial of British coronavirus vaccine widens to 10,000


Oxford University and AstraZeneca on Friday said that partner institutions across Britain had started recruiting up to 10,260 adults and children in Britain for trials of an experimental coronavirus vaccine.

The trials which on Thursday received U.S. backing worth up to $1.2 billion will be carried out to see how well the human immune system responds to the vaccine and how safe it is.

An initial trial that started on April 23 has already seen more than 1,000 volunteers aged 18-55 receive the injection and Oxford said phases II and III will add people aged 56 and older as well as children of 5 to 12 years.

AstraZeneca has already signed up Britain and the United States as partners to mass produce the vaccine in anticipation of confirmation that it works and is safe to use.
