I can't comment on the first question because I am not over PMR yet. To the second question, no I do not get a flu shot. I got the shots yearly when I worked in health care because it seemed like the right thing to do to protect patients. About half the time I would have a reaction to the shot and feel ill for a couple of days. I always got the shot on a Friday so I would not have to work when I wasn't feeling well. In spite of the shots I twice got the flu, was sick for at least a week with temps up to 102. Then in 2020, the Covid year, I got my flu shot and had a worse than normal reaction, spiked a fever for 5 days straight. My Covid test was negative. In early 2021 I got the Covid vaccine and PMR shortly after. I told my rheumatologist that I am not getting any vaccines for the time being and he did not give me any flak about it when I explained my reasons. I think in general vaccines are good but they aren't always appropriate for everyone. I haven't had any colds or flu since 2021. I don't fly on planes. I do shop, eat in restaurants and attend meetings as much as I want.
