Myth #5: We don’t know how long the vaccine protection will last.

Fact: Researchers have good reason to predict that HPV vaccine protection will last for at least 15 years, and probably all life long.

Researchers predict this because the HPV vaccine causes an immune response similar to that seen with other vaccines.
We know from the vaccine studies that there is good protection for 5 years and that the antibody level is much higher after vaccination than after natural infection with HPV. This is good news as a high antibody level usually means longer protection.
Follow-up studies are being done to see if there will be a need for a booster dose in the future.
The HPV vaccine will protect girls now. It’s far better to give the vaccine and then give a booster in the future, if needed, than not to give the vaccine at all.
