Lessons learnt from a measles outbreak in Madang Province, Papua New Guinea, June 2014 - March 2015
This study examined measles vaccine wastage during an outbreak response in Madang Province of Papua New Guinea from June 2014 to March 2015. Interviews and data reviews were conducted with all 48 health centres involved in the outbreak response. Of the 154,110 doses issued by Madang Province during the outbreak, a total of 85,236 (55%) doses were wasted. The wastage varied by district from 31% to 90%. The total cost of the vaccine wastage was estimated to be 589,810 Kina ($196,604 USD). Regular audits of cold chain logistics, staff training and improved processes for recording vaccine administration and wastage will decrease vaccine wastage during vaccine-preventable disease outbreaks and also benefit routine immunization activities.
