The first trial among more than 1,000 adults in Britain found that the vaccine-induced “strong antibody and T cell immune responses” against the novel coronavirus.
A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.
The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.
The authors of the studies said that they encountered a few adverse side effects from the vaccine candidates.
However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.
Co-author Sarah Gilbert from the University of Oxford said the results “hold promise”.
“If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at a large scale.”
