In response to the "Anonymous" post, - I understand that you are responding with the only information you and the rest of us have been handed. I can understand that with this information, not vaccinating can seem like a scary thing. This is where you must research before you can argue. There are too many parents who have children injured by vax to say it's not a huge problem. Many parents who have had to make use of a little white casket due to vaccinations. As for Polio, there has not been a documented case of wild Polio since the 1979 - every case there after was caused by the Polio vaccine. There is so much evidence against vaccines that I could sit here all night. It would really be worth your time to investigate and formulate your own opinion.
