BOGOTA, Colombia and VANCOUVER, Canada – Anvisa, Brazil’s health care surveillance agency, re-started phase III trials for Coronavac, the COVID-19 vaccine candidate developed by China-based Sinovac Biotech Ltd., after a suspension of just two days. “Anvisa understands that it has sufficient subsidies to allow the resumption of vaccination,” the regulator said on Nov. 11. Anvisa said it plans to continue monitoring “the possible relationship of causality” between an unexpected serious adverse event and the vaccine.
