This fact sheet describes a phase 4, post-licensure influenza vaccine effectiveness study that PATH and its partners are conducting in Senegal. The study seeks to better understand the extent of the influenza disease burden in tropical Africa, as well as the potential of current seasonal influenza vaccines to reduce influenza-related deaths in the developing world. Ultimately, study data could help public health officials decide how to best use influenza vaccines in Senegal and in similar tropical countries.

Keeping heat-sensitive vaccines at the right temperature is crucial yet often difficult in areas with limited or no electrical power. Project Optimize collaborated with the Vietnam National Expanded Programme on Immunization to evaluate two technologies to respond to this challenge. One was a direct-drive solar refrigerator and the other a passive cooling device. This fact sheet describes the lessons learned from the demonstration—information which can be used by other country programs considering these devices for long-term storage of vaccines.

PATH’s Vaccine Resource Library (VRL) seeks to gather the world’s best immunization resources in a single, easy-to-use website. The VRL offers a wide variety of high-quality, scientifically accurate documents and links on specific diseases and topics in immunization. It is geared for health professionals in the developing and industrialized worlds, as well as for journalists, policymakers, community leaders, parents, and others interested in vaccine-related resources. The resources found on the VRL are collected from a variety of sources, including news media, scientific journals, and leaders in public health.

Commissioned by project Optimize, a collaboration of PATH and the World Health Organization, a study of vaccine vial monitor (VVM) availability and use in developing countries in four regions was undertaken. The study had three aspects: the total proportion of vaccines with VVMs in the regions with detailed information by country, in-depth information on policies and practices, and knowledge and attitudes in a selected sample of countries.
