Gardasil®9HPV Vaccine Description For 2022

Merck's Gardasil®9 vaccine helps protect people ages 9 to 45 against the following diseases caused by nine types of human papillomavirus (HPV): cervical, vaginal, and vulvar cancers in females, anal cancer, certain head and neck cancers, and genital warts in both males and females. Gardasil9 consists of HPV proteins, Types 6, 11, 16, 18, 31, 33, 45, 52, and 58, amorphous aluminum hydroxyphosphate sulfate, yeast protein, sodium chloride, L-histidine, Polysorbate 80, sodium borate, and water for injection.

Most sexually active persons become infected with HPV at least once in their lifetime. Approximately 100 types of HPV have been identified, at least 40 of which can infect the genital area, says the U.S. CDC. Most HPV infections are self-limited and are asymptomatic or unrecognized. However, many females with cervical cancers were probably exposed to cancer-causing HPV types in their teens and early 20s. This is because, unlike some other cancers, cervical cancer is not passed down through family genes.

Additionally, the CDC says that men can get HPV, causing anal and throat cancers and genital warts. And in 2021, the U.S. Food and Drug Administration (FDA) approved an expanded indication to include oropharyngeal and other head and neck cancers caused by HPV.

On April 11, 2022, Health Canada approved an expanded indication of GARDASIL®9 in individuals 9 through 45 years of age for the prevention of infection caused by HPV and the following diseases associated with the HPV types included in the vaccine: Oropharyngeal and other head and neck cancers caused by HPV types 16, 18, 31, 33, 45, 52, and 58.

GARDASIL9 may not fully protect everyone, nor will it protect against diseases caused by other HPV types or against diseases not caused by HPV. GARDASIL 9 does not prevent all types of cervical, vulvar, vaginal, anal, or head and neck cancers

Merck Sharp & Dohme Corp., a Merck & Co., Inc. subsidiary, produces the Gardasil 9 vaccine.

Gardasil 9 HPV Vaccine Indication For 2022

Gardasil 9 helps protect women ages 9 to 45 against cervical, vaginal, vulvar, and anal cancers and genital warts caused by nine types of HPV. It is also indicated to help protect boys and men ages 9 to 45 against anal cancer and genital warts caused by HPV types. In addition, the U.S. FDA approved an expanded indication for GARDASIL 9 to prevent oropharyngeal cancers caused by HPV types 16, 18, 31, 33, 45, 52, and 58. The oropharyngeal and head and neck cancer indication are approved under accelerated approval based on effectiveness in preventing HPV-related anogenital disease. However, continued support for this indication may be contingent upon verification and clinical benefit description in a confirmatory trial, which is currently underway.

Gardasil 9 HPV Vaccine U.S. Dosage

The U.S. CDC now recommends that 11 to 12-year-olds get 2-doses of the HPV vaccine—rather than the previously recommended 3-doses—to protect against cancers caused by HPV. The second dose should be given 6-12 months after the first dose. Each dose of Gardasil 9 is 0.5-mL and is administered intramuscularly only. The Age Recommended Regimen Schedule: 9 through 14 years - 2-doses at 0, 6 to 12 months; 15 through 45 years - 3-doses at 0, 2, and 6 months.

Gardasil 9 HPV Vaccine U.K. Dosage 2022

The move to the 9-valent vaccine is due to commence in the current year. The 9-valent HPV vaccine is JCVI's preferred vaccine for the routine adolescent program because of the additional protection against the five cancer-causing HPV types. 

Gardasil 9 HPV Vaccine Adverse Events

Anyone who is allergic to the ingredients of Gardasil 9, including those severely allergic to yeast, should not receive the vaccine. And Gardasil 9 was not studied in women who knew they were pregnant. On April 5, 2021, the JAMA published a study, 'Association of Inadvertent 9-Valent Human Papillomavirus Vaccine in Pregnancy With Spontaneous Abortion and Adverse Birth Outcomes.' In this cohort study of 1,493 pregnancies, in adjusted analyses, during-pregnancy or peripregnancy exposures to the 9vHPV vaccine were not associated with spontaneous abortion. In addition, 9vHPV vaccine exposures during or around pregnancy were not associated with adverse birth outcomes among live births.

Gardasil 9 HPV Vaccine Side Effects

Gardasil 9 side effects include pain, swelling, redness, itching, bruising, bleeding, a lump where your child got the shot, headache, fever, nausea, and dizziness. Fainting can happen after getting Gardasil 9. Sometimes people who faint can fall and hurt themselves. For this reason, your health care professional may ask your child to sit or lie down for 15 minutes after your child gets Gardasil 9. Some people who faint might shake or become stiff.

Gardasil 9 HPV Vaccine Revenues For 2021

Merck & Co. announced on February 3, 2022, that GARDASIL / GARDASIL 9 vaccine sales grew 44% to $5.7 Billion; Excluding the Impact From Foreign Exchange, Sales Grew 39% in 2021.

March 30, 2022 - The BMJ published the findings from an Observational Study in Australia: Conclusions: Colposcopy referral thresholds need to consider underlying cancer risk; on this basis, women with HPV16/18 in the first round of HPV screening were found to be at higher risk regardless of cytology result, even in a previously well-screened population. Women with HPV types, not 16/18, and negative or low-grade cytology showed a low risk of serious abnormalities but constitute most referrals and could be managed safely with two rounds of repeat HPV testing rather than one. HPV16/18 driven referrals were low in HPV vaccinated cohorts.

March 16, 2022 - The JAMA Network published an Original Investigation that suggests the decrease in the incidence of cervical cancers, particularly in young women, may be associated with HPV vaccinations. However, it may be too early to evaluate this association in oropharyngeal and anal cancers later in life.

March 16, 2022 -  NPJ published: Precision drugging of the MAPK pathway in head and neck cancer. About one-fifth of often deadly head and neck cancers harbor genetic mutations in a pathway that is key to normal cell growth. Scientists report those mutations, which enable abnormal cell growth, can also make cancer vulnerable.

February 10, 2022 - The JCVI committee presented to the U.K. government its recommendation to move to the 9-valent vaccine. This vaccine will protect against five additional cancer-causing HPV types. 

January 1, 2022 - A new study found 'Opportunistically-detected high-grade vulvar and vaginal precancers among females aged 15–29 years decreased and anal precancers stabilized in years after introducing the HPV vaccine, which is suggestive of the impact of the vaccine on noncervical human papillomavirus cancers.'

November 29, 2021 - The JAMA Pediatrics published a Research Letter: Human Papillomavirus Vaccination and Trends in Cervical Cancer Incidence and Mortality in the US, which found a 38% decrease in cervical cancer incidence and a 43% decline in mortality among women after HPV vaccination.

The results of this study suggest that the association of current HPV vaccination trends with O.P.C. will be modest during the next 25 years because of the reduction in O.P.C. incidence associated with HPV vaccination among older adults, who have the highest incidence of disease, will take longer.'

August 26, 2021 - The JAMA Network published an Original Investigation: Association Between Human Papillomavirus Vaccination and Primary Ovarian Insufficiency in a Nationwide Cohort. This study found no association between HPV vaccination and primary ovarian insufficiency. However, given the rarity of the outcome in this study, the presence of a clinically relevant increase in the rate of diagnosis cannot be excluded.

August 23, 2021 - The JAMA Network published an Original Investigation: Incidence and Types of Human Papillomavirus Infections in Adolescent Girls and Young Women Immunized With the Human Papillomavirus Vaccine. Conclusions and Relevance: Whereas lower detection rates of vaccine-related HPV types were observed since the introduction of vaccines in female youth in New York City, rates of some nonvaccine high-risk HPV types were higher. Continued monitoring of high-risk HPV prevalence is warranted.

July 28, 2021 - The U.K. government issued an update on the universal HPV immunization program. A recent Scottish study has already shown a 71% reduction in pre-cancerous cervical disease in young women. In addition, ten years since the start of the vaccination program in the U.K., there has been a considerable decline in HPV infections and the number of young people with genital warts.

These projections are based on currently available incidence and mortality data through 2017 and 2018, respectively, and thus do not account for the impact of the COVID-19 pandemic on cancer diagnoses or deaths.

January 5, 2021 - The human papillomavirus infection, or HPV, is the most common sexually transmitted infection in the U.S., according to the Centers for Disease Control and Prevention. HPV is associated with health problems, including genital warts and cancers, but a vaccine has been available since 2006 to stop the virus. The C.D.C. reports more than 12 years of data to support the HPV vaccine is safe and effective, yet HPV vaccination rates across the U.S. remain low. Social media has a history of being a popular place for sexual health discussions, and the HPV vaccine is one of the most discussed vaccines on the internet.

October 27, 2020 -  Merck E.V.P. and chief commercial officer Frank Clyburn said during the recent earnings call that Gardasil sales fell by 10% in Q3'2020, largely due to lower demand in the U.S. and Hong Kong, S.A.R., P.R.C. attributable to the COVID-19 pandemic, partially offset by higher volumes in China and Europe.

October 8, 2020 - A new study led by Jeanine Guidry, Ph.D., compared how HPV vaccination was portrayed on Pinterest before and after the social media platform began moderating vaccine-related content. Findings may help public health officials utilize social media to tackle potentially harmful rhetoric and disseminate trustworthy health information. "Vaccine misinformation is immensely prevalent online and particularly on social media," said Guidry, who is also director of the Media+Health Lab at V.C.U. "Although the specific influence of social media on medical decision-making remains understudied, research supports an association between online health information searches and medical decisions."
