Oxford's COVID-19 vaccine trial paused over 'unexplained illness' in UK

The pause, which was first reported by STAT, will allow Astrazeneca, a British-Swedish company, to conduct a security review and investigate whether the vaccine caused the illness, How long the hold will last is unclear.

Drug companies are racing to finish a coronavirus vaccine that would bring an end to an epidemic that has already claimed quite 8,90,000 lives globally. Astrazeneca may be a front-runner, with late-stage clinical trials underway round the world, and has said it hoped to possess a vaccine ready before the top of the year. If the explanation for the reaction tums bent be associated with the vaccine, those efforts might be derailed.

Late stage vaccine testing remains crucial, as large trials can happen rare but serious side effects that might surface as long as many thousands of individuals received a vaccine.
