To maintain stability and viability, most childhood vaccines must be kept cool – both heat and freezing can ruin them. Drs. Sarkari and Coeshott and their colleagues are working to identify Pluronic polymer-based formulations that stabilize vaccines from -10°C to 45°C. Their aim is to develop vaccines that are resistant to freezing and form protective matrices at elevated temperatures. Investigators are evaluating formulations based on Pluronic F127 using vaccines for measles and hepatitis B.
