I choose to immunize because my dad has ALS and has to live in a nursing home. He's progressed so far that he can't cough without the use of this machine that blows air into his lungs and then sucks it out really fast causing him to cough. If you've ever had to press this horrific machine to a loved one's face while it does its thing and then watch them gasp for breath in between bouts, you'd understand why I immunize. If I were to carry something and he were to catch it, he WILL get pneumonia and die a painful death. That's why I immunize.
