Children and older adults are to be included in the second phase of vaccine trials to protect against coronavirus.

Axar.az reports citing foreign media.

The first phase of the University of Oxford trial began in April, involving 1,000 healthy adults aged 55 and under.

Now more than 10,200 people - including over 70s and five to 12-year-olds - will be enrolled in the study, to see the effects on their immune system.

Trials of the same vaccine on monkeys appear to have given them some protection against the disease.

The animals had less of the virus in their lungs and airways, but it is not certain this finding will translate to people.

The scientists behind the vaccine have previously said they are aiming to have at least a million doses of a coronavirus vaccine by September this year.
