Doctors have looked at 323,247 medical records to compare children under 2 years of age who were fully vaccinated at CDC recommended ages to children who were under vaccinated because of parental choice. They found that the children who were under vaccinated the most had lower impatient admission rates and significantly lower rates of outpatient and emergency department visits (Miller 18). This is largely because those children who are not vaccinated are not introduced to those toxins at such an early age. They have an all natural immune system that has learned how to fight diseases on its own. Those children who are vaccinated at such an early age have that virus living in their body. Their immune system has never had to fight off disease on its own, therefore, making it weaker. "A German study released in September 2011 of about 8000 unvaccinated children, newborn to 19 years, show vaccinated children were five times more likely to suffer from various diseases and disorders than unvaccinated children"
