They are checking see if the reaction was from the vaccine or something else….
This happened to a British subject…
The pharmaceutical company AstraZeneca halted global trials of its coronavirus vaccine on Tuesday because of a serious and unexpected adverse reaction in a participant, the company said.
The trial’s halt, which was first reported by Stat News, will allow the British-Swedish company to conduct a safety review. How long the hold will last is unclear.
In a statement, the company described the halt as a “routine action which has to happen whenever there is a potentially unexplained illness in one of the trials, while it is investigated, ensuring we maintain the integrity of the trials.”
