Vaccines help people become immune to diseases without having to get sick. Making an informed choice about immunization is key to protecting your family’s health. 

High immunization rates in a community also provide protection for those who cannot be vaccinated because of age restrictions or medical conditions. This is called community immunity because when most people are vaccinated, a disease cannot spread widely. The community is immune, even when certain people are not.

The Snohomish County Health Department encourages residents of all ages to get vaccinated according to national recommendations.


Vaccines are carefully developed and monitored for safety and effectiveness. Before vaccinations, many people in the United States got seriously ill or died of once common diseases such as:

  • Bacterial Haemophilus influenzae type b (hib or H flu)
  • Diphtheria
  • Influenza
  • Measles
  • Mumps
  • Rubella (German Measles)
  • Tetanus
  • Whooping Cough (pertussis)


Many diseases that are now rare in the U.S. still occur in other countries. If you are planning a trip outside of the United States, certain travel vaccinations may be recommended or required depending on where you travel.
