In the United States, vaccines have reduced or eliminated many infectious diseases that once routinely killed or harmed thousands of infants and young children each year. However, the viruses and bacteria that cause vaccine-preventable disease and death still exist and can be passed on to people who are not immunized. Vaccine-preventable diseases have many social and economic costs. These diseases result in doctor visits, hospitalizations, and even death. Sick children miss school and can cause parents to lose time from work. Vaccine your children and keep everyone healthy.
