Require all parents to vaccinate their children, or be charged with child endangerment.

Over the years, humans have been on this earth, we have developed a means to help us become immune to certain diseases, using one of our bodies most base functions of fighting off diseases our bodies have been exposed to previously. Vaccination is one of the most important things to keep us healthy and kill off deadly diseases.
Recently, however there have been many parents who are outright refusing to vaccinate their children, based on misinformation. These people have single-handedly managed to spread and bring back diseases such as whooping cough, polio, measles and mumps.
That is why we petition the Obama administration to make it illegal to not vaccinate your children. When parents refuse to vaccinate their children, they are endangering their children's lives and the lives of others.
