The Phase 3 trial of its vaccine began last month, with a goal of enrolling up to 60,000 volunteers across more than 200 sites in the United States and around the world.
“Following our guidelines, the participant’s illness is being reviewed and evaluated by the ENSEMBLE independent Data Safety Monitoring Board as well as our internal clinical and safety physicians,” the company said in a statement.
