Four-fifths of the cervical cancer burden in the world is experienced in developing countries. HPV genotypes 16 and 18 account for 70 per cent of cervical cancers and currently available vaccines targeting these two types confer a high degree of protection against HPV 16/18 infection and related cervical precancerous lesions. However, widespread implementation of HPV vaccination programs are challenged by the unaffordable high costs of the vaccines and the lack of effective vaccine delivery platforms for sexually naïve girls. Other unresolved issues include long-term protection, cross-protection against HPV types not included in the vaccine and whether booster doses will be needed. Sensitivities associated with a vaccine preventing a sexually transmitted infection in girls, lack of awareness, public demand and political will, lack of coordination between cancer control, sexual and reproductive health and vaccine delivery services are additional challenges. Reduced costs, simple vaccine regimes and strengthening vaccine delivery platforms for adolescents should eventually facilitate HPV vaccine introduction in developing countries.
