The Importance of Cold Chain Management in Protecting Public Health
Maintaining the vaccine’s efficacy requires proper cold storage conditions. The task of upholding vaccine quality is a collective responsibility, of all individual involved in the vaccine’s journey. It begins with cold storage at the manufacturing plant, continues through vaccine transportation and delivery, and concludes with the appropriate storage at the provider’s facility before administering the vaccine to patients. WHO guidelines state that vaccines should be stored within the temperature range of +2°C to +8°C throughout their lifecycle, while some vaccines require ultra-low temperature storage. A breakdown in the cold chain can lead to substantial financial setbacks and potential hazards to public health. Use our WHO recommended vaccine series data logger to monitor the temperature from start to finish.
Fulfills WHO PQS Specifications
Vaccine series data logger has been designed, manufactured, and tested in a manner that aligns with the guidelines and specifications set by the WHO PQS (Performance Quality & Safety) particularly WHO/PQS/E006. Monitoring the optimal storage conditions is essential for maintaining the efficacy and strength of vaccines.
