Vaccines prevent disease in people who receive them and protect those who come into contact with unvaccinated individuals. Vaccines are provided through injection with a needle, orally or a nasal spray.
Vaccines help prevent infectious diseases and save lives. Vaccines are responsible for the control of many infectious diseases that were once common in this country, including polio, measles, diphtheria, pertussis (whooping cough), rubella (German measles), mumps, tetanus, and the flu.
Vaccine-preventable diseases have a costly impact, resulting in doctor's visits, hospitalizations, and premature deaths. Sick children can also cause parents to lose time from work.
