The last time I caught the flu, it almost killed me. I ended up with tachycardia and A Fib.At my age and health conditions, the flu is not welcome, the last time I had it was over twenty years ago. They called it the Australian Flu. I was so sick my hair hurt. Now, it's easy for me to think of the fragile nature of my health, the asbestosis playing hell on my immune system and try to protect myself and my wife who has serious health issues, she also takes immune suppressant drugs.
Now there are 2 people in the home with chronic lung disease. When my wife had covid it wasn't too intense, I never caught it but I kept my distance. If I went into her room I would wear a mask but around everywhere else no mask. I also asked her if I could have 1 room she did not go in, she agreed. We try to protect each other.
I can see how your reaction to the vaccine would put you off. It would me. Since my wife moved here from Texas about 25 years ago, I have had numerous vaccines fortunately with no ill effects.
