Women Who Are Pregnant Or Breastfeeding

HPV vaccines are not recommended for pregnant women.

Women who become pregnant after starting the HPV vaccination course are recommended to stop the vaccination course and receive the remaining doses after pregnancy.

Women who are inadvertently given a dose of HPV vaccine around the time of conception or during pregnancy should be told that there is a large body of evidence suggesting that vaccination does not harm the mother or the fetus in these situations.

In the 9vHPV vaccine clinical trials, some women became pregnant during the trial, despite recommendations for participants to avoid pregnancy. The overall proportions of pregnancies that resulted in an adverse outcome were similar among 9vHPV vaccine recipients and placebo or control vaccine recipients.21 In addition, pooled analyses of women who became pregnant during clinical trials of 2vHPV and 4vHPV vaccines showed that, overall, there were no differences in pregnancy outcomes between HPV vaccine recipients and control vaccine recipients.22-24

Breastfeeding women can receive HPV vaccines.25

HPV vaccination is generally safe and well tolerated. The safety profile and the spectrum of adverse events after vaccination in males are similar to those in females.26,27

For all HPV vaccines, injection site reactions are the most commonly reported adverse event.21,28,29

In most clinical trials, systemic adverse events were comparable between HPV vaccine recipients and control vaccine recipients, and included:29,30

How You Can Get Hpv

HPV which stands for Human Papillomavirus is a sexually transmitted virus that you can catch from an infected person through:

sexual activity, including oral sex
intimate skin-to-skin contact with an infected person

You don’t have to have intercourse to get HPV.

Without immunization, three out of four sexually active Canadians will be infected with HPV at some point in their lives.

Extra Doses Of 9vhpv Vaccine

People who have completed the recommended number of doses of 2vHPV or 4vHPV vaccine are not routinely recommended to receive 9vHPV vaccine, because the extra benefit is thought to be marginal.

However, if the person wants protection against the additional HPV types, there appears to be no safety concerns associated with giving 9vHPV after a completed 2vHPV course. 13 The rate of injection site reactions may increase.

The Health Risks Of Hpv

HPV causes almost all cervical cancers but is also linked to cancer of the throat, oral cavity, penis, anus, vagina or vulva. More research is needed to define the extent of these linkages.

Anogenital warts, although rarely associated with cancer, are still a significant burden for those affected often leading to physical, emotional and social problems. They can be effectively treated by applying prescribed medication either in a doctor’s office or by you at home. Other medical treatments include cryotherapy , an electric current, or a laser or surgical removal of the warts but these methods do not always eliminate HPV infection. Even with treatment, warts can recur.

HPV does not appear to affect a woman’s ability to become pregnant. Although considered rare, the baby may be at risk of getting an HPV infection in the throat. A C-section delivery is not routinely recommended, unless there is a significant obstruction or other risks.

Should Hpv Vaccines Be Given To People Who Are Already Infected With Hpv Or Have Cervical Cell Changes

ACIP recommends that people who have an HPV infection and/or an abnormal Pap test result that may indicate an HPV infection should still receive the HPV vaccine if they are in the appropriate age group because the vaccine may protect them against high-risk HPV types that they have not yet acquired. However, these people should be told that the vaccination will not cure them of current HPV infections or treat the abnormal results of their Pap test .

Although HPV vaccines have been found to be safe when given to people who are already infected with HPV, the vaccines provide maximum benefit if a person receives them before he or she is sexually active .

It is likely that someone previously infected with HPV will still get some residual benefit from vaccination, even if he or she has already been infected with one or more of the HPV types included in the vaccines.

Vaccine Safety And Coverage

A 2 versus 3 dose HPV vaccine series would have an impact on the number of HPV vaccine related adverse events following immunization that are reported. While the accumulating evidence on the safety of the available HPV vaccines is very reassuring, as reported multiple times by the Global Advisory Committee on Vaccine Safety ,Footnote 58 reducing the number of doses in the series would reduce the opportunity for AEFIs. Similarly, reducing the number of doses in the series may have a favourable impact on vaccine coverage.

Common Questions About The Hpv Vaccine Schedule

ACIP makes recommendations based on the best available scientific evidence. Immunogenicity studies show that two doses of HPV vaccine given at least 6 months apart to 914-year-olds provided as good or better antibody responses as three doses given to older adolescents or young adults.

Answering parents questions: The data we have from current scientific studies show that in children age 914 years, two doses of HPV vaccine given at least 6 months apart were as good or better as three doses. The immune response for older people hasnt been studied in the same way, so information is not available for that age group. For this reason, older teens and adults should get three doses for best protection.

Yes. In a 2-dose schedule of HPV vaccine, the recommended interval is 612 months, and the minimum interval is 5 months between the first and second dose. If the second dose is given earlier than 5 months, a third dose should be given.

Answering parents questions: The recommended schedule is two doses given 6 12 months apart. The minimum amount of time between those doses is 5 months. Because your child received two doses less than 5 months apart, your child should get a third dose.

Answering parents questions: Since your child received the first dose before 15 years of age, they only need one more dose to be fully protected. However, the second dose should be given as soon as possible and not further delayed.
