Benefits of using vaccines out of the cold chain: Delivering Meningitis A vaccine in a controlled temperature chain during the mass immunization campaign in Benin.

Highlights: [•] The first field use of MenAfriVac's new label allowed the vaccine to be kept at up to 40°C for up to 4 days. [•] 155,000 people were vaccinated using the CTC approach in the Meningitis A campaign in northern Benin in 2012. [•] 98.7% of supervisors and 100% of vaccinators would prefer to conduct their next campaign using CTC. [•] They saw CTC benefits as: more people vaccinated, no need to return to health centre every night, reduced logistic burden. [•] Taking advantage of the flexibility offered by CTC opens the door for the implementation of new immunization strategies. [ABSTRACT FROM AUTHOR]
