To address these barriers to access, CHAI is pursuing four strategic objectives to support governments to increase access to immunization, ensuring that more children are protected from vaccine-preventable diseases. These objectives are to:

1. Increase the speed and efficiency with which new vaccines are introduced in developing countries;2. Enhance the performance and efficiency of vaccine cold chain and logistics systems;3. Enhance planning, resourcing, and implementation of immunization strategy; and4. Increase access to effective vaccines by negotiating lower prices for vaccines and immunization supply chain equipment.

CHAI pursues these goals through a combination of work globally and in focus countries, which include Cameroon, Ethiopia, Kenya, Mozambique, Nigeria, Tanzania, and Uganda.

1. Increase the speed and efficiency with which new vaccines are introduced.

CHAI’s work to accelerate the introduction of new vaccines is focused on the introduction of Haemophilus influenzae type b (Hib), rotavirus, and pneumococcal vaccines, which target the leading causes of child mortality: pneumonia and diarrhea. To date, approximately 135,000 deaths per year have been averted from CHAI-supported new vaccine introductions in our focus countries. In addition, CHAI is supporting governments to introduce the Inactivated Polio Vaccine (IPV) and switching the Oral Polio Vaccine (OPV) in use, which are critical steps to achieving polio eradication worldwide.
