The First Vaccine Recommended for Girls and Young Women
Gardasil 4 was the first vaccine released in the U.S. It protected against four types of HPV —6, 11, 16, and 18. Clinical trials showed that the vaccine provided nearly 100% protection against types 16 and 18, the HPV types associated with the majority of cervical cancer cases. It was also shown to be about 99% effective at preventing infection with the low-risk types 6 and 11 that cause genital warts. It was approved for use in girls and young women ages 9-26 in the US.
A New Vaccine and Approval for Males
A second vaccine called Cervarix was introduced. It protects against only two type of HPV—16 and 19—and was only approved for use in females to prevent cervical cancer. Cervarix is no longer available in the U.S. but continues to be used in other countries. In this same year, Gardasil was approved for use in boys and young men ages 9-26 to prevent genital warts.
A New Vaccine with Broader Protection
Gardasil 9, a vaccine that protects against 9 types of HPV, is released. The vaccine protects against the four HPV types in the original vaccine plus five more high-risk types (31, 33, 45, 52, and 58) that are linked to cancer, including anal, vaginal, and vulvar cancer. Scientists estimate that widespread use of this vaccine could prevent 90% of cervical cancer in the U.S.
Vaccine Available to Older Adults
The U.S. Food and Drug Administration approved expanded use of the vaccine in females and males 27-45 years old.
Vaccine Approved for Prevention of Other HPV-Related Cancer
While originally only approved by the FDA for cervical cancer prevention, the FDA expanded its approve of Gardasil 9 to include prevention of vaginal, vulvar, anal, oropharyngeal, and other head and neck cancers.
Continued Progress Needed
We can eliminate cervical cancer with widespread early vaccination! NCCC will continue to educate and advocate for HPV vaccination and cancer prevention.
