reading about the immune system is making me sick...

I really don't want to know HOW my immune system works or WHY it works. I feel achy and ill learning about it. As long as it works, I don't care. I just don't want to know!

I'm currently reading the chapter in my Health book about vaccinations and infectious pathogens. Just the words about needles, medicines, dead microbes, cell damage, parasites, system structures, and donated blood plasma is making me hurt all over.

Is there a vaccine for that?
