"Unexplained Illness" Led to Pause of Johnson& Johnson Coronavirus Vaccine


A pause to the US' s Johnson & Johnson vaccine issued after one of volunteers fell unexplained illness.

The pharma giant said that the pause in the trial, which is aiming to enroll 60,000 people to determine if the vaccine is safe and effective, was first reported by Stat News' Matthew Herper. 

On Monday the company announced that it had temporarily halted its coronavirus vaccine trials after a participant experienced an unexplained illness, the second major setback to hit a late-stage test of a coronavirus immunization. 

However, Johnson & Johnson has not said what type of illness the participant of the 60,000-person trial encountered. Further details, including the age and the gender of the participant, have also not been revealed. J&J said the participant's illness is being reviewed by an independent board as well as by company doctors. 

"We must respect this participant's privacy," J&J said in a statement. "We're also learning more about this participant's illness, and it's important to have all the facts before we share additional information."

J&J, the world's largest healthcare company, started its late-stage trial in September to determine whether the shot can prevent COVID-19. The trial had initially expected to yield early results by the end of 2020.

In September, AstraZeneca paused the trial after a participant had a potential adverse reaction.
