Today's shot was quite painful going in and is quite sore now. Hopefully, that will pass without worse effects. It's much worse than either Covid shot. I don't recall that with past flu shots but YMMV.
Scheduled for our flu shots tomorrow (Kroger required an appt, unlike in the past, but at least the paperwork was finished online). I never notice the flu shots, whether the injection site itself or any side effects, while the wife always does. Regarding the Covid shots from Moderna I did notice some and the wife very little. Go figure.
I'll echo what others have said. Get the flu shot since this might be a tougher season than most, particularly with the colder weather scheduled for much of the country. Best wishes.
Is there a "theory" other than cold weather (I assume, folks staying in-doors to avoid the cold) as to why the flu might be worse this year? I was thinking it's perhaps because many have abandoned their Covid rituals (masks/distancing/no-crowds/etc.) to resume a more "normal" life. IIRC last year flu was WAY down - I think that may have been attributed to Covid routines but not sure. YMMV
This Canadian doctor details a few reasons why the flu season might be worse than last winter, including schools being hotbeds for the virus, as well as our systems going "soft" from not enough exposure to germs, etc over the past year. https://finance.yahoo.com/news/montreal-doctor-raymond-rezaie-explains-203500725.html
