The short explanation
The HPV vaccine works best when given before someone becomes sexually active, because it protects against infection rather than clearing existing HPV. However, it can still be useful for some women who are already sexually active, as they may not have been exposed to all the HPV types the vaccine covers. Many guidelines recommend the vaccine up to age 26, and some allow it up to 45 after discussing the possible benefit with a doctor. The benefit is usually smaller at older ages. Whether you get the vaccine or not, regular cervical screening remains important, because the vaccine does not protect against all cancer-causing HPV types.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- The vaccine is given as a course of injections, the number depending on age; your doctor can explain.
- It is not given during pregnancy, so tell your doctor if you might be pregnant.
- Costs vary; ask whether it is available through government programmes in your area.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell how much you would benefit. A doctor can discuss it with you based on your history.
Questions for your clinician
