One of the main reasons why the HPV vaccine is age-limited is that by the time most people are 26, they will probably have already been exposed to the types of HPV covered by the HPV jab. Initially, the vaccine was also age-limited because scientists hadn't spent as much time testing the efficacy of the HPV in older people to see if it worked well enough for approval. That additional research was eventually performed; however, and the result was that in April 2011 the FDA denied Merck's expedited application to expand labeling to include women over the age of 26.
As for men, although they do get HPV-related diseases, they are less frequent, and scientists are still debating whether vaccinating men is cost effective. That having been said, the HPV vaccine was recently approved for young men for the prevention of genital warts.
Still, there are many older women, and some older men who would like to get the HPV vaccine right now. Is it possible? The answer is: maybe. Even if you can, however, the experience of getting the HPV jab won't be the same as that of a younger person because the inoculation cost (which is substantial) is going to come out of your pocket.
How do you find a clinic that will vaccinate you, when you're over age? You'll need to do a lot of legwork. I've discovered that some (but not all) Planned Parenthood clinics will give the HPV vaccine to women over the age of 26. Policy varies both state by state and clinic by clinic. Call first, and be prepared to have them change their mind when you show up in their office... it happened to me.
Your physician may also be willing to give you the HPV vaccine in his or her office, but, because you are over the approved age, the cost will probably not be covered by insurance. It's not cheap. The HPV vaccine is approximately $215 per shot, about $650 for the three shot series, and that does not include any costs for the three visits.
My experience has been that if you're willing to do the legwork, and possibly a bit of traveling, most people who really want the HPV vaccine can find someone who will vaccinate them. Whether the vaccine will do you any good, well, that's another matter entirely. Part of being an adult is choosing that risk, and covering the HPV vaccine cost, for yourself.
Note From Your Guide - 10/29/11
I have reports from several users that their insurance companies have fully covered their HPV vaccination expenses, even though they were outside the recommended age-range for the HPV vaccine. Therefore, it is definitely a good idea to have your doctor check with your insurance company to see if HPV vaccination will be covered. You may be able to save yourself a substantial amount of money. Thank you to everyone who has brought this to my attention
