I got the flu and Covid at the same time this year, just different arms. No problems.
I get them all. About the only thing I get is a sore arm.
I'm allergic to flu shot ended up in hospital from reaction so no go for me. 2 weeks after getting my covid shot booster I had a massive seizure and was lifeflighted and went into cardiac arrest for 3 minutes I'll never take one again the only shot I do is Kesimpta with no side effects otherwise I'm just cautious I drink vitamin water, Dr has me on regular vitamins.I worked in healthcare most my life you never stop practicing universal precautions even when u can't work no more it's just programmed
I DON'T shots i was told long time ago not to get a flu shot at MAYO hospital were i use to go so I don't get any of them.it works for me.
I still get a bruise after the flu shot.
