To date, on-label delivery of vaccines in a Controlled Temperature Chain (CTC) in AFRO has been as follows :

CTC was adopted for Meningitis A vaccination (Menafrivac) campaigns in Benin (2012), Mauritania (2014), Togo (2014), Cote D'Ivoire (2014), South Sudan (2015), and DRC (2015).  Uganda piloted CTC with HPV4 (Gardasil) in 2017.  Plans are under way to roll out HPV delivery through CTC in additional countries.  A pilot to implement CTC with Oral Cholera Vaccine (Shanchol) is scheduled for Q3 of this year.

Off-label delivery is a much broader concept and given its unregulated nature, is much harder to track and quantify.

All the best,
