Vaccine Safety – Spoilage

The AP reported today that children in several cities have been called back for repeat vaccination after being administered shots using vaccines that have not been maintained at a temperature to prevent spoilage. Inadequate refrigeration can cause vaccines to lose potency. The AP story describes thousands of children requiring re-immunization in several states over the past few years.

An organization called PATH has solved this problem for third world countries. For the past 10 years they have been using a vial monitor sticker about the size of a dime that adheres to the vaccine vial and changes color as the vaccine is exposed to heat. The color alerts the health-care worker if the vaccine is not safe to use for immunizations. PATH worked with WHO and TEMPTIME Corportion to develop the the monitors called (HEATmarker – TM) which are printed on the vaccine vial labels and add only a few cents to the price of the vial. These monitors have saved immunization programs world wide, millions of dollars .

If PATH can solve the problem in remote villages with sporadic electricity in Ghana, we should be able to do as well in the US.

    Who should you contact at the FDA to follow up on this great idea?

    CDC is not a regulatory agency. FDA is the regulatory agency for vaccines.

    interesting. people in economics and sociology love these examples, sometimes they call them “leapfrogging”

    Leapfrogging is a theory of development in which developing countries skip inferior, less efficient, more expensive or more polluting technologies and industries and move directly to more advanced ones.
