While the CDC has never conducted a study of vaccinated children versus unvaccinated children, a group of researchers in the Netherlands has. They looked at a comparison of babies born to mothers who were vaccinated or not vaccinated for certain vaccines. They found that the babies born to mothers vaccinated for certain diseases, such as measles, had lower maternal antibodies than babies born to mothers who were not vaccinated. Heidi Stevenson of Gaia Health provides a great analysis and commentary of the study. - See more at: http://healthimpactnews.com/2013/vaccines-reduce-newborns-disease-immunity-study/#sthash.zFkcyugJ.dpuf
