Two very effective prevention strategies for cervical cancer exist - vaccination against the human papillomavirus (HPV) and cervical screening with primary HPV testing followed by treatment of precancerous lesions. In 2018, the World Health Organisation called for action towards achieving the global elimination of cervical cancer, and a strategic plan encompassing elimination goals and targets for the scale-up of HPV vaccination, cervical screening and precancer and cancer treatment, particularly in low and middle income countries, will be presented to the 2020 World Health Assembly. ⋯ However, there are significant challenges - (i) including vaccine manufacturing pipeline, supply, delivery and hesitancy, (ii) cervical screening HPV self-collection and point-of-care evaluation, acceptability, and scaling up effective precancer treatment processes, (iii) configuration of appropriate referral pathways, cancer treatment services and palliative care for those women who do develop cervical cancer, as well as (iv) the effective financing of both HPV vaccination and cervical screening on a large scale. It is hoped and anticipated that the WHO elimination initiative will galvanise concerted action to address these issues.

Compare the effectiveness of community-based HPV-related education and onsite school-based vaccination versus community-based education only for increasing HPV vaccine uptake in a rural, medically underserved area. ⋯ The school with on-site vaccination events and community-based education had a higher adolescent HPV vaccination rate compared to schools that received community-based education only.

Rubella vaccine was not part of national immunization programs (NIP) in several countries in the Middle East and North Africa (MENA), South-East Asia (SEA), and South Africa regions until the year 2000. Therefore, immunization coverage of females older than 20 years old in these countries has been the focus of national campaigns for rubella elimination in developing countries. Vaccines against human papillomavirus (HPV) are not part of NIPs in developing countries. ⋯ In addition, pro-inflammatory cytokines IL-4, IL-6, IL-2, and IFNγ levels were significantly higher in mice immunized with the combined vaccine than control groups. Overall, the combined vaccine was safe and immunogenic offering antibody protection as well as eliciting a cellular immune response against rubella and HPV viruses in a single vaccine. This combined vaccine can be of great value to females above 20 years old in the SEA, MENA and South Africa regions offering coverage to rubella vaccine and a potential increase in HPV vaccine uptake rates after appropriate clinical testing.

Randomized Controlled Trial Multicenter Study
Efficacy, immunogenicity, and safety of a 9-valent human papillomavirus vaccine in Latin American girls, boys, and young women.
A 9-valent human papillomavirus (HPV6/11/16/18/31/33/45/52/58; 9vHPV) vaccine was developed to expand coverage of the previously developed quadrivalent (HPV6/11/16/18; qHPV) vaccine. ⋯ The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Latin American young women, girls, and boys. These data support 9vHPV vaccination programs in Latin America, a region with substantial cervical cancer burden.
