Single-dose human papillomavirus vaccination in low- and middle-income countries : time for implementation?

Although cervical cancer is becoming a rare disease in high income regions, it is still a major health issue in low-and middle-income countries (LMICs). Cervical cancer develops after infection with a high-risk human papilloma virus (hrHPV), an infection against which vaccination has been possible since 2006. Large population immunization programs have been organized in many higher income countries, and yet they have not been implemented in most of the lower and middle-income nations. The cost of the vaccine, as well as the need for two doses impedes coverage in the most vulnerable groups. Studies are suggesting the efficacy of single dose vaccination, but so far only observational data are available while large, randomized, double-blind studies are still ongoing. In order to prevent and combat this disease, it is essential to inform the population of vaccination benefits and offer accessible programs in higher as well as low-and middle-income countries. In this commentary, we wish to focus our attention on the case for implementing single dose vaccination in lower-and middle-income nations.Although cervical cancer is becoming a rare disease in high income regions, it is still a major health issue in low-and middle-income countries (LMICs).
