Safety surveillance of the influenza vaccines

An annual flu vaccine safety survey is completed by over 20,000 people across Canada who receive their flu vaccine. The purpose of the online survey is to monitor adverse events (side-effects) after the flu shot and allows us to monitor the safety of the flu vaccine used in Canada each year.

Dr. Julie Bettinger presents findings from the safety survey at the Canadian Immunization Conference 2016. Of 200 abstracts, this study was chosen as one of the Top 10 Scientific Abstracts of 2016.

In 2015, nearly 15,000 adults responded to the online survey, most did not report any health events after the flu shot. 95% of the unvaccinated control group did not report a health events compared to nearly 97% of the vaccinated group. Overall, no safety concerns were detected for the 2015 flu vaccines.
