To identify and describe implementation of slate-level informed consen
t requirements for adolescent immunizations, current stare regulations
on informed consent and immunization services for children and adoles
cents were identified through the LEXIS-NEXIS(R) legal data base. Regu
lations were coded for informed consent characteristics, consent exemp
tions, and current immunization requirements. Stare immunization progr
am directors, project managers, and state hepatitis coordinators were
surveyed to catalogue how regulations were implemented and document ne
w policies or regulations under consideration. Parental consent for im
munizations is standard practice in 43 states. Most states (n=34) requ
ire separate consent for each injection when more than one injection i
s required to complete a vaccination, but only for a limited number of
medical procedures. Nine states allow adolescents to self-consent for
hepatitis B vaccination in sexually transmitted disease clinics and f
amily planning clinics as part of the exemption for miners' receipt of
sexual health services. Most states require consent for vaccination s
ervices provided to adolescents. Parental consent requirements are a p
otential barrier to vaccinating adolescents in some settings.
