How does Gardasil 9 work? And how long does it take to start working?
Gardasil 9 is a vaccine that helps prevent certain conditions caused by HPV.
Gardasil 9 works by causing your immune system to make antibodies (a type of protein). These antibodies help fight off HPV and protect your body from an HPV infection. When you’re protected against HPV infection, you’re less likely to develop other conditions that HPV may cause.
Gardasil 9 starts helping your body make antibodies after your first dose. It may take several doses for your body to make enough antibodies to fully protect you against HPV. Gardasil 9 is usually given as a series of two or three doses over 6–12 months.
To learn more about how Gardasil 9 works, talk with your doctor or pharmacist.
Uses of Gardasil 9
The Food and Drug Administration (FDA) approves vaccines such as Gardasil 9 for certain conditions. Gardasil 9’s approved use is described below.
Note: Sex and gender exist on spectrums. In this article, we use the terms “female” and “male” to refer to a person’s sex assigned at birth.
Use for prevention of certain conditions caused by human papillomavirus (HPV)
Doctors may prescribe Gardasil 9 vaccine to help prevent certain conditions caused by human papillomavirus (HPV). It helps protect against nine types of HPV. The age limit for Gardasil 9 is adults and children ages 9–45 years.
Specifically, Gardasil 9 is used for the prevention of:
- certain cancers or spots that may turn into cancer in females, including those that affect the anus, cervix, head and neck,* vagina, or vulva
- certain cancers or spots that may turn into cancer in males, including those that affect the head and neck* or anus
- genital warts
HPV is a group of viruses that can lead to HPV infection. HPV can spread from one person to another through skin-to-skin contact, often through sexual intercourse.
With HPV, you likely won’t have any symptoms. But some types of HPV can lead to genital warts and increase the risk of certain cancers. These include cancers of the anus, cervix, head and neck, vagina, and vulva.
Doctors may not prescribe Gardasil 9 vaccine in certain situations, such as for:
- replacing screenings or treatments for cancer or spots that may turn into cancer
- protecting against HPV exposure that occurred before the vaccine was given
- protecting against other types of HPV or cancers
* Gardasil 9 has received accelerated approval from the FDA to help prevent head and neck cancer, due to its effectiveness for this use. Accelerated approval is based on information from early studies of the drug. It’s granted for drugs that are used to treat conditions that don’t have a lot of effective treatment options. The decision for full approval of Gardasil 9 for preventing head and neck cancer will be made after more studies are completed.
