There are a few reasons why it's important to still have regular Cervical Screening Tests even if you have had the HPV vaccine (Gardasil).
Firstly, the HPV vaccine only protects against some types of HPV. There are several other types of HPV not covered by the vaccine that can cause cervical cancer.
There is also the chance that you may have been exposed to HPV through sexual activity before you had the vaccine. The HPV vaccine doesn't treat HPV infections you already have.
In addition, you can still have an abnormal Cervical Screening Test result after you have had the vaccine.
