The Partnership for Influenza Vaccine Introduction (PIVI) is a key program of The Task Force for Global Health. An innovative public-private program, PIVI works in partnership with the Centers for Disease Control and Prevention (CDC), Ministries of Health, corporate partners and others to create sustainable, seasonal influenza vaccination programs in low- and middle-income countries. PIVI works in concert with WHO programs to help countries prepare for pandemic influenza and to support countries’ efforts to control and prevent seasonal influenza. PIVI assists each partner country with a multi-year plan for influenza vaccination through technical assistance and time-limited provision of donated or low-cost vaccines.
