Thank you for your query at DoctorSpring.com
I understand your concern.
The issue with infections such as HPV or HSV ( Herpes infection ), is once you get infected, you remain infected for the rest of your life. Being a viral infection, they have no cure. However, that does not mean you will spread the infection everytime you try to be intimate with your partner. Some people with good immunity have one outbreak, and do not show any further outbreaks for the next 5-6 years, and can have sex without worrying about the infection. Just like herpes, periods of stress or other concurrent illness, trigger an outbreak, so the immunity plays an important part. In some odd cases though, the transmission happens even without any active lesion. So, it is better to use condoms as far as possible, and if there are skin lesions on the thighs, or other areas, it is better to avoid intercourse completely till the lesion disappears. Aldara cream helps in quick recovery.
Regarding the vaccine, now, since you are already infected, it won't be that helpful. Vaccines do prevent against the cervical cancer strains such as HPV-6,11 and hence all women are supposed to be vaccinated. For you, I will advise you to first confirm the strain, which can be done in good laboratories, and based on that we can decide on the future course of treatment.
Please apply Aldara as soon as you see a possible lesion of HPV, as it helps in quicker recovery and prevents recurrence.
Hope this was helpful,
