Gardasil- What's Up Down Under?

The HPV (Human Papilloma Virus) vaccine, Gardasil, was FDA approved in the United States for use in young women in June, 2006, then extended for males in October, 2009. In October of 2011, the Advisory Committee on Immunization Practices (ACIP- the group that creates our national guidelines that you see posted on your doctor's office walls) extended their official recommendations to include ROUTINE VACCINATION of both boys and girls at age 11-12 years, with "catch up" immunizations for those youth  ages 13-21 who had missed getting this vaccine series.

Why are we vaccinating?
We vaccinate primarily for CANCER PREVENTION. Each year in the United States, we have over 33,300 cases of HPV-related cancers (data from CDC, 2012). About 2/3 of these occur in women, primarily with cervical cancers, but also other genital, anal and oral cancers. In men, the majority of HPV related cancers are oral, but they, too, can have genital and anal cancer, though it is less common than in females.
Gardasil also protects against the two strains of HPV that cause 90% of genital warts, and with over one million cases of this malady each year in the US, you can see what an impact prevention can make here!

How well are we doing?
Not as well as we could do...because national immunization surveys have shown that in teenagers 13-17 years old, only 53% of young women had started the series, and only 1/3 of that group had completed the series. A bit more encouraging is an improvement in the very low percentage of teenage males getting the vaccine, which was at 8% in 2011 (the first year it was considered a "routine" universal vaccine) and more than doubled to over 20% in 2012.

How effective is this vaccine? Here is the GREAT news- the HPV vaccine is unbelievably effective when given to young adults not previously exposed to HPV (with no prior sexual intimacy). The CDC's data demonstrates efficacy nearing 100% protection for women in preventing cervical, vulvar & vaginal cancers and genital warts, and 90% efficacy in men for genital wart prevention and 75% efficacy preventing early anal cancers.

What happened down under? 
From 2007-2009, Australia provided the HPV vaccine free of charge to all young women ages 12-26, and had extremely high vaccination rates as they utilized the school system to give out these shots. Follow up studies in 2011 and 2012 showed dramatic results, with 92% decline in genital warts in young women (< 21years old),  72% decline in women ages 21-30, and interestingly...an 81% delicate in young (< 21) heterosexual men and 51% decline in men ages 21-30. This is interesting because the young men saw improvement not because they had been immunized, but simply from the widespread immunization of all the women. Pre-cancerous cervical abnormalities also markedly declined in this short time period, and since cervical cancer typically is very slow growing, we expect to see dramatic falls in cervical cancer rates in the next few years and certainly, in the next decade.

BOTTOM LINE: HPV vaccination SHOULD BE a routine immunization for our sons and daughters- talk to your family physician about it at your next visit*

(In this day and age, I feel compelled to add two things: one, I in no way financially benefit from the makers of the Gardasil vaccine; two, yes, we chose to vaccinate our daughters.)

Gardasil & Increased Promiscuity? NOT an Issue

The Gardasil vaccine is back in the news. Gardasil is the vaccine recommended for both boys and girls to protect them against the Human Papillomavirus (HPV), which causes genital warts and cervical cancer) Yesterday, an article published in Pediatrics confirmed that girls who had received this vaccine did not, in fact, have any increased sexual promiscuity compared with their peers who did not receive the vaccine. Why was this study done? One reason for lower vaccination rates with this recommended vaccine (compared to other vaccines recommended in this age group) was parental concern that giving their preteen and teenage daughters this shot would appear to be giving "permission" to be more sexually active since they would be protected.

This study looked back at roughly 1400 girls over three and a half years. Almost one third of these girls received the Gardasil vaccine, while the other 2/3 did not. After the immunization, medical issues that can result from increased sexual activity- pregnancy and sexually transmitted diseases- were measured and compared between groups. Results? No significant difference in the two groups.

The results are not surprising, but I am happy to have this data to help reassure any parents who may have this concern. I have not yet found a teen who believes that the Gardasil vaccine somehow makes them bullet-proof in the sexual arena, although I have seen many who falsely believe condoms will do so- but that is a different discussion. If teens are aware of Gardasil, they know it is "for cancer". Only the rare teen (and parent, frankly) seems to realize that this vaccine also protects against genital warts- a disease that affects over a MILLION sexually active people each year in the United States; a disease that often destroys the self-image of young people just as they are trying to make critical life decisions. Genital warts make people feel "dirty" and "gross", and although we can treat warts to make new outbreaks resolve more quickly, we do not have a cure. And if you've ever had a wart frozen off your knee or finger, you know it hurts, so add painful plus embarrassing when that wart is in the genital area.

BOTTOM LINE: Gardasil is recommended as part of our routine vaccinations for both girls and boys to protect them from HPV-related cancers and genital warts. If your child is not yet vaccinated, talk with his or her doctor at the next visit.

HPV Vaccine (Gardasil)- Don't Forget the BOYS!

I'll bet you could quote the commercial for the HPV vaccine, Gardasil, about choosing to be "one less"- one less woman to get cervical cancer. This is one time where I am pleased that the media is playing a role in pharmaceutical awareness! We absolutely want EVERYONE to know about cervical cancer and the exciting news that we now know not only how this cancer is caused and spread, but most importantly, we know how it can be PREVENTED.

Did you know, though, that this vaccine also protects against genital warts? Two strains of HPV (6& 11) cause 90% of genital warts. Every year there are over a MILLION cases of genital warts in the United States alone. They are COMMON. These warts are transmitted by direct skin-to-skin contact, and though this usually occurs during sex, actual intercourse is certainly not required to pass them on. They are very contagious, with estimates up to 65% transmission. Warts typically recur despite treatment, and frankly, the treatment is unpleasant at best- we burn the warts chemically or with liquid nitrogen. If you've ever had a wart frozen/burned off your knee, you know what that feels like, and the genital area has more nerve endings. Enough said!

While males don't have a cervix to get cancer, they do have other parts that get HPV-related cancers (anal & penile, as well as some head and neck cancers,) although certainly these cancers are less common. Obviously, males can also get genital warts. In my clinical experience, little harms self-image like a young person developing these genital lesions, especially because we cannot simply cure them and make them go away forever.

Gardasil was approved for use in males over a year ago. A study recently published in the New England Journal of Medicine demonstrated that the vaccine had good efficacy in prevention of genital warts in males. More on this study tomorrow...

BOTTOM LINE: PREVENTION is KEY for HPV disease- talk with your doctor (or your child's doctor) about HPV vaccinations for your SONS & DAUGHTERS.

PS. I am NOT on anyone's payroll for this vaccine- but I absolutely do recommend it.
