Got flu vaccines for most of my life and I never had the flu until 3 years ago when an unvaccinated family member brought it home. The 2 years before that and that year I did get the vaccines due to it being recommended for health reasons for myself. I become ill immediately each time I recieve the vaccine for at least 2 weeks to a month. That year I had both the flu and pneumonia vaccines and I also had frozen shoulders in both arms. Not fun. Then in May I got flu B. They said the vaccine was much less effective that year because the viruses had mutated and it is usually only about 65% effective on average. I had a high fever and a terrible cough but I was ok and I didn’t need to go to the hospital etc. The doctor I went to said it was too late for the viral treatment and I was ok etc. Now my family gets the vaccines and I don’t. I wash my hands all the time and I don’t touch things like door knobs when I’m out. If I do hands are washed immediately with probiotic cleansers.
