Everything you need to know about the trial results for a new coronavirus vaccine
In an interim analysis of a phase 3 clinical trial conducted in the UK, the vaccine has been shown to be nearly 89% effective, with 27% of participants in the trial – almost 4,000 people – older than 65. That trial suggested that it was 95.6% effective against the original coronavirus and 85.6% effective against the more recent UK strain. Those results were based on the first 62 cases of Covid-19 identified among volunteers, with 56 cases among those given a placebo against just six in those given the vaccine.
