Optimal storage of vaccines and reliable cold chains

More than 150 companies and institutes worldwide are conducting research on the development of new COVID-19 vaccines. And more and more are reporting promising results. A crucial factor in protecting the efficacy of vaccines during production, storage and transportation is the monitoring of defined temperature limits – ranging from 2 to 8°C to extreme lows of -80°C, depending on the vaccine. Testo offers the appropriate measuring technology to ensure that vaccines are not impaired by temperature fluctuations:

  • Solutions for environmental and temperature monitoring from production through to administering the vaccine 
  • Products and solutions from USB loggers to fully integrated monitoring systems 
  • Tailor-made services and personal advice from our experts.

More reliability in temperature monitoring of vaccines

Environmental and temperature monitoring in refrigerators and freezers

If vaccines are exposed to the wrong climatic conditions, their stability and efficacy can suffer – with fatal consequences. It is therefore essential that all major climatic parameters are monitored to ensure the high quality standards are met. A key factor in this is maintaining and documenting defined constant temperatures for the sensitive vaccines as well as ensuring there is an uninterrupted cold chain throughout the entire product cycle:

  • Clearly defined climatic parameters and temperature limits must be maintained in all stages of production.
  • It is imperative that there are no fluctuations in temperature and climatic conditions during storage and transportation and that this can be verified. 
  • Be it a vaccination centre, nursing home or doctor's surgery, where vaccination is concerned, it is essential that the vaccine is fully monitored to ensure its proper storage and refrigeration before being administered to people.

Measuring solutions from Testo will enable you to ensure both the quality of vaccines and stable climatic parameters.

Temperature monitoring during transportation of vaccines

Headline-Application-2-Landingpage-2000x1500px.jpg

Different vaccines place different demands on transportation conditions. Particularly sensitive vaccines actually require continuous refrigeration at temperatures as low as -80°C. Even small violations of the temperature limits can be detrimental to vaccines. GxP-compliant quality management therefore defines monitoring of the entire cold chain – from production of vaccines to administering them to people in clinics, doctor's surgeries or specially equipped COVID-19 vaccination centres. Measuring instruments from Testo are a valuable aid in this process. They ensure high-precision monitoring of the cold chain, which in turn guarantees the reliable efficacy of the vaccines for all requirements:

  • Refrigerator temperatures from 2 to 8°C
  • Freezer temperatures of from -18 to 0°C
  • Extreme temperatures as low as -80°C.

 

Regardless of which climatic parameters need monitoring – Testo has the right solution.
