NPR on Aug 20, 2010 aired a story whether boys should also get vaccinated for HPV. It is well established that vaccines like Gardasil (FDA approved for boys last year) and Cervarix protect against two of the HPV types (HPV-16 and HPV-18) that can cause cervical cancer and some other genital cancers including anal, vulvar, vaginal, and penile cancers.
However, it may potentially prevent other types of HPV related disorders (NOT mentioned in the NPR story) involving the head & neck in both men and women, including:
Respiratory Papillomas (benign)
Throat Cancer
Oral Cancer (tongue, tonsil, salivary gland)
Oral ulcers/lesions/warts (benign)
According to epidemiological studies, there has been a dramatic increase in cancer involving the salivary glands and tongue attributed to HPV and were of squamous, acinar, and mucoepidermoid morphologic types. This increase in oral cavity cancer has occurred mainly in the 10-40 years age group and suspected to be secondary to increased acceptance of oral-genital sexual practices.
What is my personal feeling on whether boys should get vaccinated? I believe the answer is yes.
In order to receive the beneficial effect of the vaccine, the vaccine needs to be given in 3 doses (at $130 per dose) ideally between ages 9-26.
