is one of the best ways to help protect against cervical cancer in the future (through early detection). A Pap test can’t diagnose HPV. But it can look for abnormal cells (that may be caused by HPV) in the lining of the cervix before the cells become precancersPrecancersPrecancers are highly abnormal cervical cells that have a high likelihood of becoming cervical cancer.

According to Canadian Cancer Society, it is recommended for all sexually active women from age 21 to be screened every 1-3 years. Precancerous changes in the cervix are quite common, can develop at any age, and are often not associated with symptoms but can be visualized by an abnormal Pap test. HPV infection is the main precancerous risk factor for the development of cervical cancer, but it is not the only one. Hence, even women vaccinated against HPV should continue to perform regular Pap tests. Speak with a healthcare professional to see what is recommended for you.

For girls who are not old enough for a Pap test, regular wellness visits are a good way to start lifelong, healthy habits.

In girls and women ages 9 to 45, GARDASIL® helps prevent infection caused by HPV types 6, 11, 16 and 18 and the following diseases associated with the HPV types included in the vaccine: cervical, vaginal, and vulvar cancers caused by HPV types 16 and 18; abnormal and precancerous vaginal and vulvar lesions, abnormal and precancerous cervical lesions as found in Pap tests, caused by types 6, 11, 16 and 18; and genital warts caused by types 6 and 11.

In girls and women ages 9 to 26, GARDASIL® also helps protect against anal cancer caused by HPV types 16 and 18, and abnormal and precancerous anal lesions caused by types 6, 11, 16 and 18.

In boys and men ages 9 to 26, GARDASIL® helps protect against infection caused by HPV types 6, 11, 16 and 18 and the following diseases associated with the HPV types included in the vaccine: anal cancer caused by HPV types 16 and 18, genital warts caused by types 6 and 11, and abnormal and precancerous anal lesions caused by types 6, 11, 16 and 18.

GARDASIL® helps prevent these diseases, but it does not treat them. And just like all vaccines, GARDASIL® may not fully protect everyone who gets it. GARDASIL® does not protect against all types of HPV. Duration of protection continues to be studied. GARDASIL® does not protect against other sexually transmitted infections.

Even if vaccinated with GARDASIL®, it is still important for women to continue having regular Pap tests. Recipients of GARDASIL® should not discontinue anal cancer screening if it has been recommended by a healthcare provider. Vaccination with GARDASIL® is not recommended during pregnancy.

Like all vaccines, GARDASIL® may cause some side effects. GARDASIL® has been shown to be generally well tolerated in adults and children as young as age 9. The most commonly reported side effects included pain, swelling, itching, bruising and redness where the shot was given, fever, nausea, dizziness, headache, vomiting and pain in extremity.

Fainting has been reported. Fainting can occur after vaccination, most commonly among adolescents and young adults. Although fainting episodes are uncommon, vaccinees should be observed for 15 minutes after they receive GARDASIL®.

Allergic reactions that may include difficulty breathing, wheezing (bronchospasm), hives, and rash have been reported.

These were not all the side effects reported. If you notice any unusual or severe symptoms after receiving GARDASIL®, contact your healthcare professional as soon as possible.
