In 1994, Michigan learned that immunization rates in the state were the lowest in the nation. In response, a partnership of public and private sector organizations – the Alliance for Immunizations in Michigan (AIM) – was formed to focus on a broad spectrum of immunization issues in Michigan. Given the low vaccination rates in Michigan at that time, the initial focus of AIM was to emphasize provider education in an effort to reduce missed opportunities to immunize. The AIM coalition’s concerted efforts were integrated into what became known as the AIM Provider Tool Kit, a comprehensive resource for immunization management, parental education, as well as other high-quality information sources. The initial printing of the AIM Provider Tool Kit consisted of 5,000 kits and has grown in each successive year; over 8,000 kits were distributed in 2006. Today, the AIM coalition continues its focus on improving all facets of immunization services in Michigan. AIM’s mission is to promote immunizations across the lifespan through a coalition of healthcare professionals and agencies. Specific goals include: 1. Raising the age appropriate immunization levels of all Michigan children to at least 90%; 2. Raising awareness among health care providers and the public of the importance of immunization across the life span; 3. Promoting participation in the Michigan Care Improvement Registry (MCIR) by all health care providers; and 4. Expanding AIM coalition education and development to include at least two presentations annually directed toward improving the coalition’s proficiency and activities. The AIM Provider Tool Kit will continue to be a mainstay of the coalition’s efforts, with expanded access through the AIM website.
