HPV & Cervical Screening
Human papillomavirus (HPV) is one of the world’s most widespread viral infections. It is easily passed on from person to person, and without vaccination almost everyone will come into contact with it at some point in their life.
HPV for the majority of the population is not a case of if, but when, you get it.
The HPV vaccine prevents a person from HPV types that cause several cancers in both men and women, including:
There is no effective screening or testing for anal, vulval, penile or throat HPV-related infections or cancers, as there is no swab or blood test that can check for all HPV types and also because, in some people, the virus is "hibernating" at levels that are not detectable by testing. Therefore vaccination, ideally before ever having sex, is highly recommended and is the most effective way of preventing HPV.
Vaccination is not a substitute for cervical screening. This vaccine protects against most, but not all, HPV types that cause cervical cancer. While most HPV-related cancers cannot be screened for, the cervical screening programme detects precancerous cervical changes.
Vaccination is most effective when given prior to HPV infection i.e. before becoming sexually active. For people who are already sexually active, the vaccine may still be of benefit. This is because there are many strains of HPV. The vaccine can still protect us against those strains (that the vaccine covers) that we haven't yet been exposed to.
It is highly effective.
Almost all HPV infections that cause abnormal cells and cancer can be prevented by the HPV vaccine.
The vaccine is very safe and no different from other common vaccines. The most common side effect is soreness at the injection site. Millions of doses have now been given all over the world. As for all medicines and vaccines, ongoing surveillance continues to monitor safety.
Current data suggests the vaccine protection is ongoing for many years. Completing the primary vaccination course (2 or 3 doses depending on age) is expected to offer lifelong protection.
Trick question! There is no single HPV test (such as a blood test or swab) to check for all HPV types at multiple body sites. Also, HPV is good at "hiding", and may only be present at undetectable levels. This means there is no test that can help answer the questions “Do I have HPV?”, “Does my partner have HPV?”, “Has my HPV gone?”.
Therefore, HPV testing is not required before vaccination.
As HPV is common and unavoidably - and often unknowingly - shared once you start having sex, if you are not vaccinated you are at risk of catching the HPV virus.
If you know that you are pregnant then delay starting getting the vaccine until after pregnancy.
If you have already had one or two doses, and then discover that you are pregnant, then wait until after pregnancy until receiving the subsequent dose/s.
If you had your vaccination and didn't realise that you were pregnant at the time, don't worry, the vaccine is safe. In the clinical trials, there were many pregnancies that occurred in the trial participants and there were no adverse effects to fertility, pregnancy, or baby.
Women may safely breastfeed if they receive the vaccine during that period.
People think that the vaccine is not required because children are not sexually active, but there are very good reasons for the vaccine to be given at an early age.
All vaccines need to be given prior to exposure of the infection that you are trying to protect against.
The best immune response to a vaccine is before around the age of 12 years. This means that vaccines work best at an early age and will provide the most enduring protection.
The HPV vaccine has been tested in children down to 9 years of age. The clinical trials included girls and boys aged from 9 years of age, who were tested for their immune response to the vaccine and followed up for safety. The group who received the vaccine in early adolescence has now been followed as young adults, with no development of the HPV infections covered by the vaccine.
Males are now included in the HPV vaccination programmes because research shows that HPV infection is shared during sexual activity and males are at risk of HPV anal, penile and throat cancers. It is highly recommended that parents consider getting the HPV vaccination for their boys.
There is no evidence that the HPV vaccine given at age 11 or 12 years has any bearing on when or how much your child becomes sexually active. In fact, research has shown that girls who have been vaccinated against HPV have subsequently made more responsible decisions regarding their sexual health compared to unvaccinated girls. There are other vaccines given for infections associated with sexual transmission e.g. Hepatitis B, and none of them have been shown to influence the future sexual behaviour of the child who has it.
In New Zealand, the HPV vaccine (Gardasil) is available and is funded for some people. Read on more for information about the cost of the HPV vaccine for those who aren’t funded, and where to find the HPV virus vaccine.
HPV is the 'common cold' of being sexually active. This means that the virus doesn't care who we are or who we choose to have sex with. Most of us will be sharing HPV with our fellow human beings.
Males carry an equal risk of acquiring HPV.
