Immunization Practices Advisory Committee (IPAC) statement: out of cold chain (OCC) and controlled temperature chain (CTC) use of vaccines

The following statement has been prepared by the CTC working group, which has been established under the authority of IPAC. The mission of this working group is to convene key stakeholders to define a shared vision and strategy for CTC. Members of the group include subject matter experts from IPAC member institutions or from their affiliates (WHO, UNICEF, Gavi, IFPMA, DCVMN, MSF, PATH). The working group provides manufacturers with the possibility of bilateral, confidential discussions regarding vaccine labelling consistent with CTC usage.
