The CDC and doctors know that you are still pretty goo goo ga ga over your child at two months so the easiest thing to do is tell you it is mandatory for you to get this vaccine. So every two months you come into the office to get your baby's shots.
The worse thing is that more and more pediatricians are denying care to parents who decline vaccinations. These parents do not just wake up one day and decide not to vaccinate. They spend hours among hours researching the pros and cons. And as my disclaimer says I am not telling you not to vaccinate I am simply saying do your homework. In most states you do have the option to decline vaccination(s) based on religious/philosophical beliefs or medical exemptions in order for your child to attend public school/daycare/college etc. This can easily be found online. No matter what you decide for your family do not let coercion by your doctor, friends, or family make your mind up for you. Do your research.
