The cancer preventing HPV vaccine, known as
Gardasil, Silgard, or
Cervarix, is one of the very
few ways available to actually reduce the risk of certain cancers. The vaccine reliably blocks HPV infections, which are directly linked to several dangerous cancers such as cervical cancer.
Unfortunately, most boys in the United States aren't receiving the cancer-preventing HPV vaccine according to a new survey of teen vaccination from the CDC. This low HPV vaccine uptake may result from the failure of physicians to recommend the vaccine or adequately explain its benefits to parents.
HPV and the cancer-preventing vaccine
Genital human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the USA. There are more than 40 HPV sub-types that can infect the genital areas of males and females. Additionally, some HPV types can also infect the mouth and throat. HPV is generally transmitted from personal contact during vaginal, anal or oral sex.
HPV is linked to cancers in men and women, and because there are so many subtypes, research has established which HPV types are linked to certain cancers. HPV is believed to cause nearly 5% of all new cancers across the world, making it almost as dangerous with regards to cancer as tobacco. If you are looking for an actual way to prevent cancer, the HPV vaccine is one of the handful evidence-based methods to block some dangerous cancers.
In 2012, cervical cancer killed over 4,000 women in the USA. About 70 percent of cases of cancers in the tongue and throat are caused by HPV–and for boys, those type of cancers are as dangerous and life-threatening as cervical cancers are to women. Many other cancers, like anal, penile, and vulvar, all disfiguring and dangerous, are related to HPV infections. And they all can be prevented by HPV vaccinations.
Since the HPV vaccine may prevent up to 90 percent of HPV-related cervical cancers, saving thousands of lives every year, it is troubling that not every boy and girl in the USA (or anywhere else in the world) is vaccinated against HPV.
Even more concerning is the fact that not every physician who takes care of these children aren't strongly recommending it every day to every patient under their care.
About the surveys
Surprisingly, according to the study published in Pediatrics, about 24% of parents whose 13- to 17-year old sons had not received the HPV vaccination stated that the reason they didn't get the shot was because their health care provider didn't recommend it.
Let that sink in for a minute or two. One-quarter of kids who did not receive a long-term cancer preventing vaccine were not advised to do so by a physician. Pardon me, while I hit my head against the desk.
Admittedly, there were a number of other reasons why parents didn't have their children vaccinated against HPV. About 19% of parents believed that the vaccine was unneeded (and I contend that if physicians were willing to discuss the vaccine that number would be quite a bit lower). About 16% didn't know enough about the vaccine (again, physicians could lower this rate). And finally, about 7% had safety concerns.
About that last point. Almost all of the myths about the HPV cancer preventing vaccine (and Gardasil specifically) have been thoroughly debunked. But once again, the pediatrician or family physician could have reduced or eliminated the parental concerns about these myths.
It's clear that the physician is the weak link in the chain of support for getting children vaccinated. This survey indicates that the bulk of the reasons for parents not insisting on the vaccine lies with the physician.
Now, let's be clear that the HPV vaccine uptake is going up, though not as fast as it should be. The CDC reports that the uptake increased by over 8% from 2013 to 2014 in boys who received at least one HPV vaccine dose (out of the recommended 3 doses). That adds up to around 42% of boys 13-17 years old who have at least one dose.
The numbers are improving, but they're not great.
There was one really great piece of news in the study. The researchers found that boys are more likely to be vaccinated against HPV if they are black, Hispanic, or in a single-mother or poorer family.
Part of the reasons for this higher uptake in those groups may because of the Vaccines for Children Program or the Affordable Care Act (commonly known as Obamacare), both which provide scheduled vaccines for free to low-income families. However, this is just a bit of a strawman argument, since most health insurance plans, whether for privileged upper classes or for working class individuals, cover the cost of childhood vaccinations.
Nevertheless, even though it's for free, it's impressive that some parents reject the myths surrounding the HPV vaccine, and prefer that their children be protected against future cancers. Maybe they have better physicians more willing to provide accurate information.
Because the research also show some doctors may be reluctant to recommend the HPV cancer preventing vaccine because they fear of offending parents. I'm troubled by this reason, because sometimes physicians should offend the parents. What if the parents reject an appropriate treatment for a disease? Or not provide adequate nutrition? Wouldn't the physician "offend" the parents in those cases? So why wouldn't they "offend" them to recommend a cancer preventing vaccine?
Debbie Saslow, director of breast and gynecologic cancer for the American Cancer Society, stated that "providers have this perception the HPV vaccine is different than other vaccines. They think parents are more concerned about it, and they're worried parents aren't going to bring their kids back if they recommend it."
I hope that's not the case. Concern about the long-term health of the child should trump a desire to keep a patient. This is troubling thought.
We have tons of evidence that the cancer preventing HPV vaccine is safe and effective. Parents should understand this. But physicians should be leaders in medicine, and make it their goal to stop this deadly disease.
