Shots in the Dark is an amazing film with an interesting history... it was never released.
You can get it, though, from their website, and I highly recommend every parent watch the following 8 films... or buy it yourself.
I'm not saying to not vaccinate, I am begging you to question and educate before you stick that needle into your or your child's skin. You can't undo a vaccination. Be prepared to assume all risks in the event one occurs to your family.
