If you have already come into contact with the HPV types that are in the vaccine it may not give you any more protection against another infection. However, we do not know exactly what type of HPV you may have now, or have had in the past. This means that the vaccine might offer some benefit to some people.
It is a very safe vaccine. It is offered to girls and boys aged 12-13, men who have sex with men and some transgender people.
If you did want to have the vaccine, this means you would need to pay for it. Some GPs and pharmacists will offer this service.
If you are under 25 and did not have the vaccine when you were younger, you can have it for no charge with your GP.
