You will need vaccines throughout your life. Vaccines in infants and children provide protection before they come in contact with potential life-threatening diseases. As an adult you need to keep your vaccinations up to date because immunity from chilhood vaccines can wear off over time. There are also other diseases you are at risk for as an adult. Vaccination is one of the safest preventive care measures available. 

Disease prevention is the key to public health. It is always better to prevent a disease than to treat it. Vaccines are responsible for the control of many infectious diseases that were once common in this country, including:

  • Diphtheria
  • Haemophilus influenzae type b (Hib)
  • Measles
  • Mumps
  • Pertussis (whooping cough)
  • Polio
  • Rubella (German measles)
  • Tetanus
  • Varicella (Chickenpox)
