If you are around old people or really young people (or people with immune deficiency issues) you really should.
How about if you
are old people?
Years ago, I took my Doctor's advice and got the flu shot. That year, I got the flu worse than I'd ever had it in my life. (I'd only ever had a flu once before that, to my recollection). So from then on, I refused to take it.
Until last year. My GP urged me to take it last year, knowing that I refuse it every year. It was already half way through the flu season and some blood work came back with results he didn't like, so I had to see him again. Nothing to do with the flu, but while I was there, he reminded me that I was 71, and this particular strain for flu seemed to want to kill old people. I still refused. But he sent me to a specialist for my thyroid (regarding the questionable test results referenced above, and an Xray that he ordered). I call her Doctor Hottie. Doctor Hottie convinced me to get a flu shot.
So I got one again this year. Oddly enough, I got even older since the last one. Doctor Hottie will be proud of me when I see her for a follow up next month.
