Human Papillomavirus (HPV) Vaccines For 2022
Vaccination against human papillomavirus (HPV) is recommended to prevent new infections and associated diseases, including cancers, says the WHO. There are safe and effective HPV vaccines to protect males and females against cancers caused by HPV.
These vaccines include 9vHPV, 4vHPV, and/or 2vHPV, says the U.S. Centers for Disease Control and Prevention (CDC). In the U.S., HPV vaccination for adolescents has been recommended for females since 2006 and males since 2011. As of February 17, 2022, the updated HPV vaccine recommendations and dose schedules for adolescents and adults in the U.S. are found on this CDC website.
The U.K. publishes its HPV vaccination advice at this link, and Canada at this link. On April 11, 202, the WHO's Strategic Advisory Group of Experts on Immunization concluded that a single-dose HPV vaccine delivers virus protection comparable to 2-dose schedules.
HPV Preventive Vaccines - Approved For 2022
Gardasil - Merck's Gardasil® vaccine consists of 4 proteins of HPV types 6, 11, 16, and 18. Gardasil is highly efficacious in preventing virus types 16 and 18 infections responsible for approximately 70% of cervical cancer cases globally. In addition, the quadrivalent vaccine is also highly efficacious in preventing anogenital warts, a common genital disease virtually always caused by infection with HPV types 6 and 11. Unfortunately, Gardasil is not available in Canada.
Gardasil 9 - Gardasil®9 consists of HPV proteins, Types 6, 11, 16, 18, 31, 33, 45, 52, and 58. HPV infections can lead to certain cervical cancers. Many females with cervical cancer were probably exposed to cancer-causing HPV types in their teens and early 20s. Additionally, males can get HPV, causing anal and throat cancers and genital warts.
Cecolin - Innovax's Cecolin HPV Vaccine protects women against HPV 16 and 18, two HPV types causing 70 percent of all cervical cancers, the third most common cancer among women. Starting May 18, 2020, the HPV vaccine developed by Chinese researchers is available in the provincial Maternity and Child Healthcare Hospital in Wuhan.
Cervarix - GlaxoSmithKline's Cervarix is a non-infectious recombinant, AS04-adjuvanted vaccine that contains recombinant L1 protein, the major antigenic protein of the capsid, of oncogenic HPV types 16 and 18. This HPV vaccine was pulled from the US market on 10/2016.
Walvax Biotechnology's recombinant bivalent HPV vaccine is effective against HPV strains 16 and 18, which China's National Medical Products Administration approved on March 25, 2022.
HPV Therapeutic Vaccines - Candidates

Ginder, MD, Chair in Cancer Research and co-leader of the Cancer Prevention and Control research program at VCU Massey Cancer Center. Fuemmeler and his team conducted the first-ever systematic review of area-level data reported in the United States between 2006 and 2020 to determine how geography, neighborhoods, and sociodemographic factors impact HPV vaccination rates among adolescents and young adults. The study was published in Cancer Epidemiology, Biomarkers, and Prevention. "Our findings demonstrate the need to adopt geospatial, standardized, and collaborative approaches in future studies that allow for the effective mapping, detection, and reporting of geographic areas with low HPV vaccination coverage," Fuemmeler said.
January 20, 2021 - Robert L. Coleman, MD, chief scientific officer of The US Oncology Research, explained that 2021 is expected to be a banner year for cervical cancer treatment. "Other essential things that are happening in cervical cancer this year would be the continuous move of immunotherapies into earlier lines of treatment, all the way up to not only in the adjuvant setting but also with chemoradiation or radiation plus [immunotherapy], followed by maintenance therapy. [There is] the concept of moving maintenance therapy into cervical cancer and earlier therapy lines, which will be an important addition. We'll hear data starting to emerge from those kinds of strategies. That's going to be really exciting for cervical cancer; we just haven't had anything for quite a while for that space."

January 8, 2021 - From bad to worse II: Risk amplification of the HPV vaccine on Facebook. Conclusion: Nearly four out of every ten Facebook posts about the HPV vaccine contained messages that amplified the risk of the HPV vaccine, and the data suggest that these posts had momentum over time. Research must continue to address the perception of vaccine safety. The vaccine is perceived as the health threat, with deep research into online communities to discover the perceived ripples and impacts.
January 7, 2021 - The NEJM reported 'Two cases of pediatric lung cancer (in 23-month-old and 6-year-old boys) resulting from mother-to-infant transmission of uterine cervical tumors were incidentally detected during routine next-generation sequencing paired samples of tumor and normal tissue. Spontaneous regression of some lesions in the first child and the slow growth of the second child's tumor mass suggested alloimmune responses against the transmitted tumors. In addition, immune checkpoint inhibitor therapy with nivolumab led to a strong regression of all remaining tumors in the first child.'
January 6, 2021 - The US Department of Health and Human Services, Office of the Assistant Secretary for Health (OASH), Office on Women's Health is launching the HPV VAX NOW campaign with the long-term goal of increasing human papillomavirus (HPV) vaccination rates among young adults ages 18–26. The campaign will specifically target young adults and healthcare providers in Mississippi, South Carolina, and Texas — states with some of the country's lowest HPV vaccination rates. Currently, fewer than half of young adults in the United States have received one or more doses of the HPV vaccine, and only 22% have completed the vaccine series. According to the Centers for Disease Control and Prevention, HPV causes nearly 36,000 cases of cancer in men and women each year in the US.
January 5, 2021 - Monique Luisi, an assistant professor at the University of Missouri School of Journalism, has studied more than 6,500 public HPV vaccine-related posts on Facebook from 2006 to 2016. In a previous study, Luisi used these Facebook posts to identify a negative trend on Facebook related to how people perceive the HPV vaccine. She suggests this negative trend on Facebook may also cause people to develop a false perception of the vaccine's health risk. After looking at the percentage of posts that made the vaccine seem more dangerous, less dangerous, or neither, Luisi found nearly 40% of Facebook posts about the HPV vaccine amplified a perceived risk. In addition, the data suggest these posts had momentum over time.
January 1, 2021 - American Academy of Pediatrics study: Antibody responses persisted through 2 to 2.5 years after the last dose of a 2-dose 9vHPV vaccine regimen in girls and boys. In girls and boys, antibody responses generated by two doses administered 6 to 12 months apart may be sufficient to induce high-level protective efficacy at least two years after the second dose.
