"Freezing vaccines is a widespread problem worldwide. Several studies over the last decade show that freezing conditions occur all along the vaccine supply chain and can compromise the potency of freeze-sensitive vaccines.

All vaccines containing an aluminum salt adjuvant are susceptible to freezing, including: diphtheria toxoid, tetanus toxoid, pertussis, liquid Haemophilus influenzae type b, hepatitis A, hepatitis B, human papillomavirus, liquid Japanese Encephalitis, liquid meningococcal, liquid pneumococcal, and liquid rabies vaccines". - Preventing Freezing in Cold Chain Boxes and Carriers
