Ya know, its funny. I never got the flu vaccine until I had a child on the way 3 years ago. I used to get the flu once a year and multiple lengthy illnesses. Since the flu shot, nothing. That is, until last year middle of February. However, I'm not entirely convinced I didnt have Covid. I know the timeline does match up, but man I checked ALL of the boxes except the taste and smell, but I couldnt eat, so who knows.
