Oxford COVID-19 vaccine safe for people with weak immunity says Oxford Professor Sarah Gilbert

Volunteers have begun participating in Brazil's first clinical trial of Oxford COVID-19 vaccine. The ChAdOx1 vaccine technology is based on an adenovirus and it is considered very safe, even in people with a weak immune system. 'We have removed some of the adenovirus genes, so that when we use it as a vaccine, the adenovirus cannot spread through the body. That makes it very safe, even in people with a weak immune system. But because it is a live virus, it is good at inducing a strong immune response after vaccination,' said Professor Sarah Gilbert, Nuffield Department of Medicine, Oxford University. Gilbert gave a short talk while participating in an informal discussion with ambassadors of the UN member states.
