Cold Chain Compromise in Sudan Highlights Need for Stable Vaccines
What happened
UNICEF reported a compromise in the cold chain system in Sudan. This issue highlights the difficulty of keeping vaccines and medicines at the required temperatures for efficacy and safety. Separately, Stablepharma, a UK biotechnology company, began a human trial in April 2025 for a tetanus-diphtheria vaccine designed to remain stable without refrigeration.

Why it matters
The cold chain relies on uninterrupted refrigeration, which is difficult to maintain in areas with limited infrastructure like Sudan. This failure risks rendering vaccines unusable. Stablepharma's work increases interest in technologies that could bypass these infrastructure limitations, particularly in crisis zones.
UNICEF is active in the crisis in Sudan, which is monitored by the United Nations.
