Novavax Inc on Thursday started a late-stage trial of its experimental COVID-19 vaccine in partnership with the UK government's Vaccines Taskforce, sending the company's shares up 6% after the bell.
The trial is expected to enroll and test the vaccine in up to 10,000 participants aged between 18 and 84 years over the next four to six weeks.
Data from the trial will support regulatory submissions for license in the UK, EU and other countries, the company said.
