First of all, just because someone gets vaccinated, it doesn't mean they won't get sick (or won't get anyone else sick, for that matter). It's a false premise because they end up getting sick anyway. It may REDUCE the chances, but very little, and in most cases it's ineffective. If someone has a weak immune system, then a vaccination might work better for them. It doesn't mean they're cured for a year, but it'll help. As far as vaccinations causing autism and/or other problems, I don't have a clue. It may or may not. I guess it depends on the person and what they have already. I never been given the flu shot nor any other vaccinations, and my dad is a doctor with 35+ years experience. He doesn't believe in them. Neither does my mom. If you want to be vaccinated and/or make sure your kids are, go ahead. It might or might not work. A better solution is to make sure they get plenty of exercise outside (or in, depending if the weather's bad) and making sure they're eating properly. Take cold, flu, or allergy medicine when needed, but make sure to do the other 2. Best things you can do to help prevent illness.
Lastly, there should be NO federal law to dictate getting a vaccination. That is one of the DUMBEST things to put in the law books. If a hospital, clinic, or retirement home says to get a vaccination before you work for them, that's completely different because that's a private institution and they come up with their own rules (whether you like them or not). But to have the government dictate vaccinations, regardless if there are people out there that could have an allergic reaction to them (they're out there, and I know a lot of people that are allergic to them), is just wrong. For those who think there should be a law for all kids to have vaccinations, how about get your kids exposed to germs, the elements, and dirt that's outside or in? Their immune system builds if they're exposed to all that, and they're less likely to get sick. That's just common knowledge. If you're not doing that, you're abusing your kids. When they get older, their immune system will breakdown, and if they don't have a don't have a strong immune system now, a simple cold could be lethal. A vaccination is useless if nothing is being done on other fronts and it could be too late if they're not building their immune system.
So you take that idea of a federal law forcing parents' kids to get vaccinated and shove back up the $#!t shoot you pulled it from, because, regardless if vaccinations are effective or not, I and many others refuse to give the federal government any more power than what it already has. Here's my tip to you: START BEING PARENTS, KEEP YOUR KIDS HEALTHY, AND STOP LOOKING TO GOVERNMENT TO SOLVE YOUR PROBLEMS AND DO THEM ON YOUR OWN (lazy @$$es)!
