Human Pappilomavirus (HPV) is responsible for over 90% of cervical cancer, genital warts and other cancers of the vulva, throat, anus, penis and vagina. HPV vaccines first came into the scene in 2006 and are currently available as Gardasil, Gardasil 9 and Cervarix.
The vaccines have always been advocated for girls and boys between 9 and 26. The main reason being that most people will most likely have been exposed to the types of HPV covered by the vaccine. Another reason is that there have been no sufficient studies to prove how efficient the vaccine would be for people older than 26.
However, a recent study of over 3 million women conducted in Scandinavian nations set to find out the risk of adverse effects of HPV vaccination in women aged between 18 and 44. While coeliac disease was identified as a risk, it was attributed to under-diagnosis in those populations and there were no safety concerns with the vaccination in adult women.
Different countries have different policies around administration of the jab especially where government subsidies are concerned. If you are older than 26, It is highly likely that you will have to pay out-of-pocket if your insurance does not cover it. This may be anything between $25 and $200 for each of the three shots, again, depending on where you are. If you can get it, prevention has always been better than cure. You will still get some form of protection, so it is not entirely useless to get vaccinated. It is also still advised to get regular pap smears done.
