The Centre for Vaccinology of the university hospital in the Belgian city of Ghent (CEVAC) will start vaccinating its test subjects with Johnson & Johnson’s candidate coronavirus vaccine again on Thursday. On Tuesday, Ghent’s University Hospital (UZ Gent) confirmed that Johnson & Johnson’s vaccinations would be resumed on Thursday, after they had been halted following the appearance of an “unexplained illness” in a test subject who had taken part in a Phase 3 study abroad in October. On 23 October, the international headquarters of Johnson & Johnson communicated that there was no causality between the symptoms detected and the vaccine, and that the trials would be resumed.
