Back to Vaccinations. The human papillomavirus HPV vaccine is given as an injection into the upper arm: 2 doses are needed, with at least 6 months between them. The 1st dose of the HPV vaccine is offered to girls and boys aged 12 and 13 years in Year 8 of school. People who have the 1st dose of the HPV vaccine at 15 years of age or above will need to have 3 doses of the vaccine. Girls and boys who became eligible for the HPV vaccine in Year 8, but missed having their doses at school, can get the vaccine up until their 25th birthday.
The vaccine contains proteins that are similar to each of these nine types of HPV. Gardasil 9 protects against HPV-related anal cancer and head and neck cancers in males and females. These cancers can be caused by HPV types 16, 18, 31, 33, 45, 52, and For two HPV types 16 and 18 , clinical studies of Gardasil were used to show the effectiveness of Gardasil 9.
In the Gardasil clinical studies , more than 24, people received Gardasil, and a similar number received a placebo an injection with no vaccine. Gardasil was found to be effective in preventing HPV-related abnormal changes or cancer in the cervix, vulva, or vagina.
Based on results of the studies described above, Gardasil 9 is also considered effective in the following age groups:. Gardasil 9 is approved to prevent genital warts caused by HPV. HPV is not the only cause of genital warts. For this purpose, clinical studies of the now-discontinued Gardasil vaccine were used to show the effectiveness of Gardasil 9.
These studies showed the vaccine provided protection against HPV types 6 and In females ages 27 through 45 years old, Gardasil was between In males and females ages 9 through 15 years, studies looked at genital wart infections that occurred after vaccination and lasted for at least 1 year.
No cases were observed in this age group after vaccination with Gardasil. In males ages 27 through 45 years, studies looked at whether Gardasil triggered a response from the immune system that was strong enough to protect against genital warts.
Gardasil 9 was found to stimulate a strong immune response in this age group. HPV can cause abnormal changes in your cervix, vulva, vagina, or anus. Some of these changes are called neoplasia, and they can lead to cancer in some people. By getting the Gardasil 9 vaccine, you can protect yourself against some of the HPV types that may cause these changes.
Clinical trials showed the effectiveness of the Gardasil 9 vaccine at preventing certain abnormal growths or changes caused by HPV. These are the HPV types whose effects are not prevented by the now-discontinued Gardasil vaccine.
In the study, 5, females received the Gardasil 9 vaccine. In this group, there was one case of cervical intraepithelial neoplasia or adenocarcinoma. In comparison, in 5, females who received the original Gardasil vaccine, there were 27 cases of cervical intraepithelial neoplasia or adenocarcinoma.
Other studies looked at Gardasil to show the effectiveness of Gardasil 9. This was done because the Gardasil vaccine and Gardasil 9 vaccine both protect against the four types of HPV covered in the studies: 6, 11, 16, and In these clinical studies , more than 24, people received Gardasil, and a similar number received a placebo an injection with no vaccine. Gardasil was found to be effective in preventing HPV-related precancerous or abnormal lesions caused by those four types of HPV.
Gardasil 9 is approved for use in children ages 9 years and older. The CDC recommends the Gardasil 9 vaccine for children ages 11 or 12 years old. However, the CDC states that some people may benefit from getting the vaccine as early as age 9. Drugs made from chemicals can have generic forms , which are exact copies of the active drug in the brand-name drug.
So, instead of generics, biologics have biosimilars. Gardasil 9 can cause mild or serious side effects. The following lists contain some of the key side effects that may occur while taking Gardasil 9.
These lists do not include all possible side effects. For more information on the possible side effects of Gardasil 9, talk with your doctor or pharmacist.

Note: Sex and gender exist on spectrums. In clinical trials in females ages 9 through 15 years old receiving their first dose of Gardasil 9, With the second and third doses, the percentage of people having injection site pain was about the same as with the first dose. However, redness and swelling at the injection site seemed to happen more often with each dose.
Females ages 16 through 26 years old had similar rates of injection site reactions including pain, redness, and swelling as females ages 9 through 15 years old. In clinical studies , males receiving Gardasil 9 reported similar rates of injection site reactions as females. This includes injection site pain, redness, and swelling. Swelling at the injection site was more common in people getting Gardasil 9 at the same time as Menactra meningococcal vaccine and Adacel which protects against tetanus, diphtheria , and whooping cough.
Swelling occurred in This is compared to 9. After getting the Gardasil 9 vaccine, you may experience dizziness. You may even faint. Your doctor or pharmacist may monitor you for 15 minutes after your vaccine to make sure you feel all right.

None of the deaths reported were found to have been caused by the Gardasil 9 vaccine. According to the CDC , from December through December , there were seven reports of death after a Gardasil 9 vaccine.
During this time, about 28 million doses of Gardasil 9 were administered. After a review of each individual case of death, the CDC determined that there was no link between the deaths that occurred and the Gardasil 9 vaccines.
Vaccine safety monitoring occurs with each vaccine that is released onto the market. There is a vaccine reporting system in place to collect information about any side effects that you may experience from a vaccine. If you experience a side effect that you believe is from a vaccine, you should report it to VAERS through the website. These organizations can look into any reported cases more in depth and determine how often a reaction may occur.
If a lot of adverse reactions are reported, changes may be made to a vaccine, or warning labels may be added.
