Immunization required for entering 6th Grade

  • OR a completed official Washington State exemption form.


Vaccine and Disease Information

Tetanus, diphtheria, and pertussis (Tdap)

The Tdap vaccine protects teens against tetanus, diphtheria, and pertussis (whooping cough). Pertussis is a very serious disease that causes coughing spells that make it hard to eat, drink, and even breathe. Getting vaccinated at 11 years old not only protects the pre-teen, but helps stop the spread of disease to younger siblings and babies. Whooping cough can also cause pneumonia, seizures, brain damage, and death.


Even though your child has had many Dtap vaccines, they still need Tdap.  The medicines are in different concentrations as they get older.  (That is why the letters in a different order. Dtap is not the same as Tdap.)


Please turn your documentation from your provider into the office at Cascade before the first day of school.
