i'm an epidemiologist. this isn't the area i typically work in, but i have studied the issue of vaccines in general, since i'm a mom too :) i don't feel the slightest worry about having my child vaccinated. honestly. i know you probably don't want to take my word for it, so do your own research. you'll see! the guy who was kind of the founder of the vaccines and autism theory has admitted that he falsified data, and subsequent studies that have been performed to examine a possible relationship have turned up nothing. i think the media and special interest groups have been totally irresponsible to keep scaring people about vaccinations this way. it really scares parents who just want to do their best.
