Vaccine Maker Halts Trial Following Unexplained Illness in Volunteer

WEDNESDAY, Sept. 9, 2020 (Healthday News) -- Final testing of a leading coronavirus vaccine candidate was paused by drugmaker AstraZeneca on Tuesday after a trial volunteer experienced a serious adverse reaction.

The company did not release specifics on the case, but whether the reaction was caused by the vaccine or was coincidental is still unclear, The New York Times reported.

The pause, first reported by STAT, will allow for a safety review and investigation of what caused the illness.
