Scientists Create Heat Resistant Vaccines for Developing World

concertina226 (2447056) writes "Iowa State University researchers have created the first heat resistant "nanovaccines" to help doctors vaccinate people in developing countries, where there is limited access to cooling equipment.

Vaccines have to be kept cool, at a temperature below 8 degrees Celsius from the moment they are made until they are administered to a patient. In developing countries with hot or tropical climates, doctors working to provide emergency medical care currently face great challenges in keeping crucial vaccines from going bad.

Now researchers from Iowa State University may have cracked the problem by packing the antigen (the active ingredient in the vaccine) within nano-sized non-toxic, biodegradable polymer particles. The nanovaccines can be stored at room temperature for between six to 10 months."
