I’ve always been a take it or leave it flu shot guy. I’ve had them before but I never thought it was that necessary. So last year around November I think I was doing a routine doctors visit and the nurse asked me if I had the flu shot yet and if I wanted one. She said the doctor is really going to try to talk you into it. The doctor comes in and explains that after 5-10 years of flu shots, your body builds up more a super immunity. Anyway, he talked me into it and I got one. Now keep in mind, this is long before Anyone heard of Covid. The funny thing is my lungs have never felt right after I took that shot. It’s very strange and makes me wonder if there was some kind of Covid or similar type immunity built into the shot. Not any conspiracy theories, I’m just bewildered why my lungs have seemed weird since I got the shot. BTW I got checked a couple of weeks ago and it was negative.
