The University of Oxford’s experimental coronavirus vaccine is safe and generated a strong immune response in around 1,000 people who volunteered to help test it, researchers said, giving hope that it could help end the pandemic.The results published in the Lancet medical journal are preliminary, with the vaccine’s effect measured by the amount of antibodies and T cells it generates in the blood of volunteers – and not in any response to the virus itself.

However, large-scale trials have started in Brazil and South Africa, where infection rates are still high, and it will be possible to assess whether those vaccinated are less likely to contract Covid-19 than others.
