About the Study: QUEST (Quadrivalent HPV Vaccine Evaluation Study) is a Canada-wide study designed to evaluate whether 2 doses of the HPV vaccine are just as effective as 3 doses at preventing Human Papillomavirus (HPV) infection and cervical cancer. The QUEST study will seek to recruit 8,666 females from across between the ages of 14 to 18. Study sites are in British Columbia, Alberta, Quebec, Nova Scotia, and PEI.
Why is the study important? A 2 dose schedule instead of 3 doses of the HPV vaccine means girls would have to endure fewer shots and the program could be extended to more people including boys. Fewer doses means that middle and lower income countries are more likely to be able to afford the HPV vaccine program.
Who can participate? Females 14-18 years old who received either 2 or 3 doses of the HPV vaccine on the provincial schedule who are located in BC, Alberta, Quebec, PIE or Nova Scotia.
What does participation involve? Participating is quick and simple and can be done from anywhere. Participants are enrolled in the study for 5 years and involves completing an online survey once a year and providing self collected swabs twice a year
