Johnson &Johnson pauses COVID-19 vaccine trial over patient illness

U.S. pharmaceutical company Johnson &Johnson said Monday it had paused its COVID-19 vaccine trial because one of its participants had become sick.

"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 in a statement.

The patient's condition was being reviewed and evaluated by the ENSEMBLE independent Data Safety Monitoring Board as well as internal clinical and safety physicians, it said.
