Vaccine Temperature Stability Tool

Use this tool to calculate the stability of any GSK vaccine available in the UK. Simply type the first three letters of a vaccine (brand or generic name) in the search bar to proceed.

Prior to using this tool, please check if your query can be answered with the licensed information available in Section 6.4, Special Precautions for Storage in the Summary of Product Characteristics (SPC). Some vaccines contain additional stability information in the product SPC.

If you require any additional information, please contact GSK UK Medical Information via email medical.information@gsk.com or phone 0800 221 441.

Between MINC ºC & MAXC ºC

At what temperature was the vaccine stored or transported?

For liquid vaccines and adjuvants, an exposure to a temperature below +2°C down to 0°C is not expected to have any detrimental effect on the quality and potency as long as the vaccine does not freeze. As a conservative measure, GSK does not recommend the use of liquid vaccines for injection that have been exposed to temperatures below 0°C due to (1) potential inaccuracies and lack of consistency of different temperature-measuring devices you use and (2) the uncertainty linked to the exact period a vaccine may have been below 0°C. The actual accuracy of monitoring device you used should be considered while using this tool. In case of doubt, please contact GSK by the usual channel.
