A recent systematic review published in Lancet Global Health in July found global disparities in age-specific vaccination coverage rates between 2006 and 2014. Among the 118 million women targeted for HPV vaccination programs, only 1% were from low or low-middle income countries. More women 10-20 years old received the full vaccine course in developed regions (33.6%) than less developed regions (2.7%). The high cost of the vaccine and programmatic issues were major obstacles to introducing the vaccine in less developed regions.
