The pharmaceutical giant of the United States, Johnson & Johnson said that it has temporarily paused its Covid-19 vaccine trial after a participant became unwell. The company did not mention what the illness was.
"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," said the company as saying in a statement on Monday.
ENSEMBLE independent Data Safety Monitoring Board and internal clinical and safety physicians are reviewing and evaluating the patient's condition, added the statement.
Johnson & Johnson pauses vaccine trial after participant suffers unexplained illness: Key points
- The company's Janssen arm is developing the vaccine.
- Such trials are stopped when they pop up while doctors check to see if the illness can be linked to the vaccine or is a coincidence.
- Johnson and Johnson's Phase 3 trial started in September and it is one of six coronavirus vaccines being tested in the United States and is one of four in the most advanced, Phase 3 stage.
- This is the second Phase 3 coronavirus vaccine trial to be paused in the United States.
- AstraZeneca's vaccine trial was paused last month because of a neurological complication in a volunteer in the United Kingdom.
