A single blinded, phase IV, adaptive randomised control trial to evaluate the safety of #coadministration of seasonal #influenza and COVID-19 vaccines (The FluVID study) - ScienceDirect https://www.sciencedirect.com/science/article/pii/S0264410X23012501 “Adverse events following #SIV and #COVID19 co-administration were generally mild and occurred with similar frequency to events following COVID-19 #vaccine alone. We found no evidence to justify routine separation of SIV and COVID-19 vaccine doses.”
