Family practitioners' immunization consent practice. Washington State, 1986.

Of 400 Washington State family practitioners surveyed in 1986, 46% of those who give routine immunizations reported that they require written parental consent before administering vaccine. In all, 57% of respondents said they discuss diphtheria-tetanus-pertussis, measles-mumps-rubella, and oral polio vaccine with their patients. Nearly half provide written information on these immunizations, except for inactivated polio vaccine, for which fewer than 20% of the physicians surveyed provide verbal or written information.
