 This week is National Infant Immunization Week. In 2014, more than 600 people across the nation were reported to have measles. This is the largest number of cases in the U.S. since measles was eliminated in 2000. Giving infants the recommended vaccinations by age two is the best way to protect them from 14 serious childhood diseases. It's essential that infants receive the recommended immunizations because it's the best way to protect them. It's easy to think of these as diseases of the past, but they still exist and children in the U.S. can and still do get some of these diseases. Vaccines are the most successful and cost-effective public health tool available for preventing disease and death.
