Thermostabilizers: Protecting Vaccines Upon Cold Chain Breaks


The delivery of liquid and solid vaccine formulations to developing countries entails several challenges, one of which is cold chain breaks. Short-term exposure to higher temperatures of up to 50 – 80° C results in a large proportion of these vaccines being wasted each year. It is in the interest of patients and manufacturers alike as the latter faces the financial risk of wasted vaccines. Additionally, approval of new vaccines is restricted due to the pressure on the supply chain.

Therefore, we asked ourselves: How can we stabilize protein vaccines in liquid and solid formulations towards these temperature increases using conventional and new excipients?

In this webinar, you will learn:

  • About the challenges involved in the delivery of vaccines to developing countries and potential risks
  • How using conventional and new excipients can stabilize protein vaccines in liquid and in solid vaccine formulations upon short-term cold chain breaks
