Some volunteers participating in a Johnson & Johnson’s COVID-19 vaccine trial in Spain have dropped out of the study, days after a serious side effect was reported by a participant of a vaccine trial in the U.K.
Spanish clinical pharmacologist Alberto Boronia, the study’s lead investigator, told Reuters that some participants “called to ask us some more detail about the risk of the vaccine, whether what happened with that vaccine had anything to do with the one we are studying, these types of questions.”
