Despite ever-growing and tremendous burden of proof of vaccine safety and efficacy, parents today continue to fear this crucial practice.  Good news!  More sources to ameliorate such fears are becoming readily available for every parent to dig into.  Be informed and feel good about the choice to vaccinate.  A new site as a collaborative with "Every Child by Two" has newly opened.  I think it is a very informative and tastefully done response to the fear-tactics of the anti-vaccinationists.  Have a look for yourself at:  http://www.vaccinateyourbaby.org/  Notice particularly all the HUGE and CREDIBLE sources backing this site.
