Vaccine cold chain management was poor in two districts, with frequent breaks compromising vaccine potency, especially for storage exceeding eight weeks. Regular audits are needed to ensure proper vaccine storage practices.

Area of Science:

  • Public Health
  • Vaccinology
  • Healthcare Management

Background:

  • Maintaining the cold chain is crucial for vaccine efficacy.
  • Compliance with storage protocols ensures vaccine potency and patient safety.

Purpose of the Study:

  • To assess vaccine cold chain integrity.
  • To evaluate adherence to local vaccine storage codes of practice.

Main Methods:

  • Random sampling of general practices in two health authorities.
  • Utilized cold chain monitors for live vaccines (oral polio, MMR).
  • Conducted structured interviews to assess compliance with storage guidelines.

Main Results:

  • Compliance with storage code varied significantly (0-70%); only 37% of practices had a designated storage manager.

  • Cold chain breaches were more common in West Berkshire than Aylesbury Vale.
  • Vaccine potency was questionable in 38% of orders stored for extended periods.

    • Conclusions:

    • Poor knowledge of cold chain management was evident in both districts.
    • Extended vaccine storage (over 8 weeks) increased cold chain breaks and compromised potency.
    • Continuous audit of vaccine storage practices is recommended, potentially linked to practitioner payments.
