I do think men tend to be more stubborn than women, in the main (though personally, I hate being "told what do" as well).
My husband and and myself, both having medical issues, were perfectly happy to have both doses of the Covid Vaccine, and the Booster (and Flu jab). These latter two at the same time (one in each arm). I had some adverse reaction, but it only lasted about 24 hours.
I have seen (as I'm sure many people have) the horror stories of very bad reactions for some people after a Covid Vaccine, and I think this is adding to the fear and reluctance of some folk to take, or continue taking the vaccines!
Personally, I think dying from Covid, or suffering Long Covid is something I would rather avoid!
I've taken Flu Vaccines each year ever since I became eligible for them, so had no hesitation in getting the Covid Vaccine when it was available.
