The regular flu vaccines are [useless](https://petermcculloughmd.substack.com/p/influenza-vaccine-fails-to-stop-hospitalization). Another [study on veterans](https://www.igor-chudov.com/p/huge-veterans-study-covid-and-flu) got the same result. Useless. I didn’t keep a note on it, but the 2018 flu vaccine caused people to get more severe cases of the flu. Health Canada even delayed the roll out of that year’s flu vaccine.
