A “serious adverse event” that led Brazil’s health authorities to halt clinical trials of a Chinese-developed Covid-19 vaccine was not related to the vaccine trial itself, the director of Brazil’s Butantan biomedical institute said on Tuesday.
Brazil’s National Health Surveillance Agency (Anvisa) suspended the trial on Monday after an incident on October 29. A note from Anvisa said the trial had been paused in order to better evaluate the data and assess the risk.
But Dimas Covas, the institute’s director, told reporters at a news conference in Sao Paulo that the incident was in no way linked to the vaccine trial.
“The serious adverse event observed in a volunteer in the trial has no relation to the vaccine,” Covas said. “It was analyzed and determined that there was no relation.” (Read more from “‘Serious Adverse Event’ That Led Brazil To Suspend Sinovac Trial Has ‘No Relation’ To Coronavirus Vaccine” HERE)
