"This report makes a case for revitalizing investments in communication for immunization. It considers communication in a broad sense, including advocacy, social and community mobilization, and information, education, and communication (IEC) activities. It identifies communication challenges that affect the success of immunization services; offers evidence of the contributions of communication activities; identifies lessons learned, and suggests ways in which communication can continue to strengthen immunization programs. Without well-planned, adequately funded strategic communication, immunization programs fall short of meeting and sustaining coverage goals. Communication is particularly needed to achieve vaccination coverage in hard-toreach populations and to build trust in vaccines among those who question them. Stakeholders also need to advocate for immunization programs to persuade governments, donors, and other actors to support vaccine programs vis-á-vis other health programs and priorities." (Page 2)
