Background:

  • The National Immunization Information Hotline (NIIH) has been a key resource since March 1997.
  • It serves both the general public and healthcare professionals seeking immunization information.

Purpose of the Study:

  • To describe the operations and experiences of the NIIH over its initial two and a half years.
  • To identify lessons learned for establishing and managing similar immunization hotlines.

Main Methods:

  • Analysis of call data from the NIIH hotline between 1998 and 2000.
  • Categorization of call types, including information requests and specific immunization schedule inquiries.

Main Results:

  • The hotline handled 246,859 calls from 1998-2000, with 175,367 being information requests.
