Study Description

Brief Summary:

Background:

Certain types of human papillomavirus (HPV) cause almost all cases of cervical cancer. Vaccines that protect against HPV can substantially reduce the risk of cervical cancer. However, HPV vaccination rates are too low, especially in countries with very high rates of cervical cancer. HPV vaccines are expensive-many countries cannot afford them-more than one dose is needed, and giving multiple doses is difficult. Researchers want to find out if one dose prevents HPV infection. If it does, more people might get the vaccine.

Objective:

To find out if giving only one dose of either the Cervarix or Gardasil9 HPV vaccines work the same as giving two doses of these vaccines to young women.

Eligibility:

Females ages 12-20 who live in Costa Rica.

Design:

There are two components to the study: (1) a controlled, randomized, double-blinded non-inferiority clinical trial to compare one-dose to two-dose vaccination; and (2) a concurrent epidemiologic survey for HPV status among unvaccinated women.

The trial will enroll twenty thousand girls 12 to 16 years old residing in Costa Rica. Participants will be randomized in two stages to one of four arms (one dose of the bivalent vaccine, two doses of the bivalent vaccine, one dose of the nonavalent vaccine and two doses of the nonavalent vaccine); the first randomization at enrollment will assign participants to one of the two study vaccines and at the second visit they will be randomized to one or two doses. Girls randomized to the one dose arm will receive an active control (i.e.: Tdap) at the time of the second vaccine dose. After vaccination, girls will be followed every six months for four years.

The epidemiologic HPV survey will enroll a group of unvaccinated girls from the same geographic areas; they will range in age from 17 to 20. These women will attend two study visits six months apart to determine their HPV DNA status, there will be no additional followup. These women will be offered HPV vaccination at the enrollment and six-month study visits.

At each visit, participants will fill out a questionnaire and give a urine sample. They may give blood samples. The older participants will use a swab to collect cervical cells from their vagina....
