The Controlled Temperature Chain, CTC, is an innovative approach to vaccine management allowing vaccines to be kept at temperatures outside of the traditional cold chain of +2°C to +8°C for a limited period of time under monitored and controlled conditions, as appropriate to the stability of the antigen.

This second of three episodes shows a case study of CTC implementation during a vaccination campaign in Côte d’Ivoire, providing insight on the health workers’ perspective.
