Quality of Cold: What it Means and Why it Matters.

PRODUCT SELECTION:

Vaccine potency relies on protection against temperature extremes through proper storage at every level of the cold chain.

While the focus of temperature control is often on overheating, vaccines can be just as susceptible to freezing risks.

To help ensure vaccine efficacy, the US Center for Disease Control and Prevention (CDC) has established guidelines for temperature control neccessary to protect vaccines. The CDC has published guideline evidence to confirm that vaccines stored in refrigerators that deviate from suggested operating ranges (2°C to 8°C) can destroy efficacy and potency of temperature-sensitive vaccines.

These standards for pharmaceutical storage are expected to be implemented in the near future and will effectively eliminate vaccine and specialty pharmaceutical storage in household, commercial and dormitory style refrigerators.
