Why are vaccines important?
In the U.S., vaccines have reduced or eliminated many infectious diseases that once routinely killed or harmed infants, children, and adults. Immunizing individuals also helps to protect the health of our community. Immunization prevents disease outbreaks by minimizing the spread of infection. The United States enjoys one of the highest childhood immunization rates in the world along with record low rates of vaccine-preventable diseases. However, the viruses and bacteria that cause vaccine-preventable disease and death still exist and can be passed on to people who are not protected by vaccines. Vaccine-preventable diseases have many social and economic costs: sick children miss school and can cause parents to lose time from work. These diseases also result in doctor’s visits, hospitalizations, disabilities, and even premature deaths.
