A trial volunteer said it was a “great feeling” to be involved in the development process as new data suggested a UK-developed Covid-19 vaccine could be up to 90% effective.

Sarah Hurst, 47, took part in the AstraZeneca and Oxford University research, receiving two jabs of either the experimental vaccine or a placebo.
