Yes, all women aged 25-74 should have a Cervical Screening Test every five years, even if you have had the HPV vaccination (Gardasil).
While the HPV vaccine protects against some types of HPV, it doesn't protect against them all - and no vaccine is 100% effective. The HPV vaccine also would not have treated any existing HPV infections.
This means that regular cervical screening remains important. Testing is recommended every five years.
When you turn 25, speak to your doctor about getting your first Cervical Screening Test.
