In this Article
Does the vaccine contain thimerosal or mercury?
No, there is no thimerosal or mercury in the vaccine.
How long does vaccine protection last?
Will a booster shot be needed? The length of vaccine protection (immunity) is usually not known when a vaccine is first introduced. So far, studies have found that vaccinated persons are protected for five years. More research is being done to find out how long protection will last, and if a booster dose of vaccine will be needed.
Will girls and women be protected against HPV and related diseases, even if they don't get all three doses?
It is not yet known how much protection girls/women would get from receiving only one or two doses of the vaccine. For this reason, it is very important that girls/women get all three doses of the vaccine.
If a woman turns 27 years of age after the first dose of HPV was administered but before the next doses are administered, should the series be completed?
Yes, the series should be completed using the recommended intervals between doses, even if this means that the series is completed after a woman turns 27 years of age.
Does the vaccine protect against cervical cancer?
Yes, HPV vaccine is the first vaccine developed to prevent cervical cancer. This new vaccine is highly effective in preventing HPV infection, the major cause of cervical cancer in women. The vaccine protects against four types of HPV, including two that cause about 70% of cervical cancer.
