Inmunizaciones Ampliadas de la Familia

Welcome Cold Chain Resource Center

Today’s immunization cold chain and supply chain operations have been one of the key elements in expanding the provision of daily immunization services and allowing more people to be protected from vaccine preventable diseases. When the PAHO Immunization Unit was established in 1978, both and PAHO and national program staff understood that the immunization cold chain was the dorsal column of the program. The assure that vaccines provided the expected benefits when a patient received an immunization, scientist, epidemiologist and health staff understood that each dose of vaccine administered had to be potent for protecting the recipient against the targeted disease(s).

To achieve this objective efforts, the Comprehensive Family Immunization Unit, in PAHO, focused five pillars: A) advising countries to use good quality refrigeration equipment; B) training of health staff in managing vaccines and their equipment; C) carrying out evaluations on cold chain and supply chain operations; D) carrying out research and development in the area of cold chain technology – both soft and hard; E) improving management capacity and skills to support all operations related to the cold chain and supply chain, in order to introduce new vaccines.

We have also established a Cold Chain Blog for our health care workers to communicate with each other to seek comments or advice from other peers who manage cold chain and supply chain operations or ask PAHO IM team a question. Users can register to access the blog
