“We have temporarily suspended additional dosing in all of our clinical trials of an investigational COVID-19 vaccine, including the entire Phase 3 trial, due to unexplained illness in one participant,” he said. the group said in a statement.

This suspension leads to the closure of the online registration system set up at the end of September to recruit 60,000 participants in the framework of phase 3 of the trial, while the independent committee for patient safety was seized.

Serious adverse events are “an expected component of any clinical study, especially large studies,” Johnson & Johnson said. The company’s protocols provide for the suspension of a study to determine if the serious adverse event is related to the drug being evaluated and if it is possible to resume the trial.
