1. No medicine is 100% safe in all circumstances. Vaccines do have published risk of complications and while tiny are not zero and sometimes are greater than the risk of contracting the disease itself.
2. As a general rule, I don't want any government telling me what to put in my body or my kid's bodies. Why not ban sugar that leads to far more health conditions than some of these diseases? Why not force people to eat the government recommended ratio of fiber, fat, calories, etc.? Sure, people might be physically healthier but at the expense of freedom of choice.
3. The flu and common cold kills lots of people per year yet those vaccines are optional for adults while some are required for kids, why?
4. Vaccines are required for kids to come to public school in CA, but not required to go to placed where they're in even closer contact (sports, pools, etc.), why?
While I think free vaccines, good education and honest dialogue are important, punishing dissent doesn't seem right. I think understanding that non-vaxers have legitimate concerns helps create a better solution than enforcement and blame.
