People who have received 2 doses of HPV vaccine separated by less than 5 months should receive a third dose 6–12 months after dose #1 and at least 12 weeks after dose #2.
HPV is very common, and if you're sexually active, it's one of the risks you face. It doesn't mean that you or your partner (or previous partners) did anything wrong. Partners tend to share strains of the virus between them, which means it's almost impossible to know where the infection started.
For people ages 15-45, the HPV vaccine is 3 separate shots. The second shot is given 2 months after the first, and the third shot is given 4 months after the second shot. So, in all, it takes about 6 months to get all 3 shots. For people ages 9-14, you only need to get 2 shots.
HPV infections usually clear up without any intervention within a few months after acquisition, and about 90% clear within 2 years. A small proportion of infections with certain types of HPV can persist and progress to cervical cancer. Cervical cancer is by far the most common HPV-related disease.
A single dose of the human papillomavirus (HPV) vaccine may provide as much protection as the currently recommended two or three doses, according to a new study. A simpler dosing schedule could potentially improve uptake, thereby reducing cancers caused by the virus.
HPV can lay dormant for many years after a person contracts the virus, even if symptoms never occur. Most cases of HPV clear within 1 to 2 years as the immune system fights off and eliminates the virus from the body. After that, the virus disappears and it can't be transmitted to other people.
Unfortunately, no treatment can kill the HPV virus that causes the genital warts. Your doctor can remove the warts with laser therapy or by freezing or applying chemicals. Some prescription treatments are available for at-home use. Surgery may be necessary for genital warts that are large or difficult to treat.
In October 2018, the US Food and Drug Administration announced it had expanded the approved age for the HPV vaccine up to age 45 for women and men. In June 2019, a key advisory committee for the US Centers for Disease Control and Prevention (CDC) recommended the vaccine for all men and women up to age 26.
Galloway noted that for a two-dose schedule to be as effective, it has to be timed just right. “The normal schedule is zero-two-six [months zero, two and six] but if you just take zero and two, that's not as good,” she said. “You need a longer interval between the two doses to develop a memory response.
Both men and women can contract HPV from having vaginal, anal, or oral sex with an infected partner. Most people infected with HPV unknowingly pass it on to their partner because they're unaware of their own HPV status.
It's only been a few years since researchers and public health officials determined that just two doses of the HPV vaccine, instead of three, are sufficient to protect people from the infection that can cause multiple cancers and genital warts, as long as they receive the vaccine in early adolescence.
The World Health Organization explained that HPV infection is so common because it can spread without penetrative intercourse – it can be passed on simply through skin-to-skin contact.
The vaccine won't protect people against types of HPV to which they've already been exposed, and many sexually active people have been exposed to at least some HPV types by their late 20s. That makes it tougher for the vaccine to have an impact in this age group.
Medications
- Salicylic acid. Over-the-counter treatments that contain salicylic acid work by removing layers of a wart a little at a time.
- Imiquimod. This prescription cream might enhance your immune system's ability to fight HPV.
- Podofilox.
- Trichloroacetic acid.
And, again, as mentioned above, the virus can be cleared by your immune system, but that does not mean you will never test positive in the future. So a negative test one time, or having a history of normal pap smears your entire life, does not mean you are in the clear forever. Can you prevent HPV infections?
There is some thought that certain B-complex vitamins are effective in boosting your immune system when it comes to fighting off HPV. These are riboflavin (B2), thiamine (B1), vitamin B12, and folate.
It usually takes around 10 years for changes to cervical cells caused by HPV to progress to cancer. Regular Pap smears are your best protection against developing cervical cancer. See your health practitioner if you ever develop any symptoms such as unusual bleeding, even if your last Pap smear was normal.
In theory, once you have been infected with HPV you should be immune to that type and should not be reinfected. However, studies have shown that natural immunity to HPV is poor and you can be reinfected with the same virus type. So in some cases the answer will be yes, but in others it will be no.
More specifically, research has shown that it is possible to transmit HPV from the fingers to the genitals. These studies have indicated that having warts on your fingers or hands is associated with an increased risk of genital and rectal HPV infections.
If you've never had any type of sexual intercourse, you're unlikely to have HPV . However, there are other risk factors for developing cervical cancer, such as family history and smoking, so talk to your doctor if you have concerns.
