The Centers for Disease Control'sJournal of Infectious Diseases
reported that, since the human papillomavirus (HPV) vaccine
was introduced in 2006, despite a vaccination rate of only 30 percent, HPV infections in teenage girls have decreased by half. The study sheds light on the potential life-saving importance of the HPV vaccine, particularly for parents who have been reluctant to have their teens receive it.
Some of that reluctance may be due to the nature of the HPV virus, which is spread through direct skin-to-skin contact during sexual activity, says gynecological cancer specialist Dr. Brent DuBeshter. Parents grapple with the idea of vaccinating a young child against a virus that is sexually transmitted. The larger point is that the vaccine is most effective when given at younger ages, and provides protection well into their adult years.
The HPV vaccine is given in a series of three shots, over a six-month period. It is generally recommended for girls ages 11 or 12, and women ages 13 through 26 years of age who have not yet been vaccinated. It is also recommended for boys ages 11 or 12, or men ages 13 through 21 if they do not receive it earlier.
HPV infection is most common in people in their late teens and early 20s. Most sexually active people will get HPV at some time in their lives, though most will never even know it. There are about 40 types of HPV that can infect the genital areas of men and women. Most HPV types cause no symptoms and go away on their own. But some types can cause cervical cancer in women and other less common cancers in both men and women.
The Society of Gynecologic Oncology recommends that girls and boys be vaccinated against HPV to prevent HPV-related cancers. These vaccines, coupled with cervical cancer screenings, would eliminate most cervical cancers. Other cancers associated with HPV including cancer of the vulva, vagina, anus, penis, and some head and neck cancers, may also be prevented with use of the HPV vaccine.
To demonstrate the vaccine’s potential for preventing cancer and saving lives, of the approximate 26 million girls under the age of 13 in the U. S.:
If none are vaccinated, 168,400 of them will develop cervical cancer and 54,100 will die from this disease over the course of their lives.
If 30 percent are vaccinated, 45,500 cases of cervical cancer and 14,600 deaths would be prevented. Each year we would see 4,400 cases and 1,400 deaths.
If 80 percent are vaccinated, 98,800 cases of cervical cancer and 31,700 deaths would be prevented.
If you’re a parent, I urge you to discuss the HPV vaccine with your child’s pediatrician or your family physician. He or she can help decide if and when the vaccine is right for your family.
