As a member of the Coalition, you will be sent action alerts asking you to contact your Congressional representatives during the appropriate time in the Congressional cycle or to sign on to letters in support of the Coalition's goals. You will also be invited to participate in periodic conference calls to share important information about critical needs of federal, state and local immunization programs, and coordinate grass-roots advocacy efforts. A key to effective grass roots advocacy is combining a national message with impacts and information from state and local organizations to their Congressional representatives. Therefore, it is just as important that the Coalition hear from local organizations about local needs in states and individual Congressional districts.
