Johnson & Johnson announced Monday they are suspending their coronavirus vaccine trial after a participant came down with a mystery illness.
“There is no greater priority than the safety and well being of the people we serve every day around the world,” Johnson & Johnson said in a statement. “We have temporarily paused further dosing in all our COVID-19 vaccine candidate clinical trials, including the Phase 3 ENSEMBLE trial, due to an unexplained illness in a study participant.”
The company said illnesses are expected in large studies, and that they “can reasonably” expect more participants to show illness symptoms. The trial was paused after the patient’s condition was evaluated by the ENSEMBLE independent Data Safety Monitoring Board. It’s unclear what symptoms the participant showed.
