Pediatricians' Immunization Consent Practices in Washington State

A survey of Washington state pediatricians and allied health professionals showed that two thirds provide written information to parents on diphtheria-tetanus-pertussis; measles-mumps-rubella; and oral polio vaccines. Twenty-two percent of pediatricians provide written information on inactivated polio vaccine. Sixty-two percent of pediatricians who give immunizations require a parent's signature as evidence of having provided information or obtained consent.
