Categorize refrigeration and chain cold immunization? please help

vaccine is only as good as the solution used to store it, as many require highly specific temperatures to remain effective. Any deviation from this can have a dramatic impact on a vaccine’s viability and, at worse, render it useless. The WHO estimates that more than 50 percent of vaccines may be wasted globally every year due to temperature control, logistics and shipment-related issues. For our part, Thermo Fisher Scientific strives to provide hospitals, doctor’s offices and pharmacies with the tools they need to deliver every vaccine at full strength and efficacy – and that starts with the right cold storage.

You shouldn’t have to compromise when it comes to storing vaccines – which is why we provide high-performance purpose built refrigerators, freezers, and ultra low freezers that are designed to meet current and impending standards from the CDC, WHO, NSF and other global agencies for vaccine storage.
