The HPV vaccine can be given to anyone, even if they are already sexually active:
If you are already sexually active, you can still get the vaccine. It will offer protection against any HPV strains you have not yet been exposed to.
The vaccine is not a treatment for existing HPV infections; it only protects against strains that have not yet been contracted.
Next Steps
The HPV vaccine is very safe, and most side effects are mild and temporary. Many people experience no side effects at all.
