Safety of co-administration of COVID-19 and seasonal influenza vaccines in individuals with autoimmune diseases from the Canadian National Vaccine Safety Network.

ABSTRACT: The Canadian National Vaccine Safety Network conducted active safety surveillance for adverse events following COVID-19 and influenza immunizations. This analysis evaluated the association between the administration of mRNA COVID-19 vaccines, influenza vaccines, or co-administration of both, and health events that prevented daily activities, caused work absenteeism, or necessitated medical consultation among individuals with autoimmune diseases. Between September and December 2022, vaccinated and unvaccinated participants from seven provinces and territories self-reported health events within 7 days post-vaccination or over a 7-day period for unvaccinated individuals. This analysis focused on individuals self-reporting autoimmune diseases. Surveys were completed by 6,506 individuals: 1,743
