Immunizations: More Education May Not Mean More Vaccination
Dr. Kronenfeld, a professor of sociology in the School of Social and Family Dynamics at Arizona State University, offered a possible explanation for the difference between the children of college graduates and those of mothers who had not graduated from high school. “There is a controversy among more educated mothers about the safety of certain kinds of immunization,” she said. “That may be part of what is going on here, but we don’t know for sure.”
College girls: if you want your children to die of the mumps instead of having a minuscule (probably non-existent) increased risk of autism, that is okay with me. However, if your children catch the mumps, that makes my (vaccinated) children more likely to catch the mumps. I don't even have children, but I still object.
