You protect your child from car accidents with seat belts, you protect them from drowning by teaching them to swim, and you can protect him or her from vaccine-preventable diseases with immunization. Vaccination against infectious diseases remains one of the most successful health interventions in the past 100 years. Countless lives have been saved as a result of vaccines. Despite that, more than 3 million people die from vaccine-preventable diseases each year. Approximately 1.5 million of these deaths are in children less than five years old. In 2014, Ohio experienced the largest outbreaks of the measles in the U.S. in 20 years. The Ohio AAP and our member pediatricians understand that parents may have concerns about vaccinating their children and we support ongoing research and increased funding in that area.
