Myth #4: There weren't any studies done in the group of girls (aged 9 to 15 years) that public health wants to vaccinate.

Fact: There were several studies in this age group. And they showed very good immune response, with the girls making high levels of antibodies against HPV.

In the studies with young women (aged 16 – 26 years), researchers were able to do both blood tests (which show antibody protection) and pelvic exams (which detect pre-cancer changes in the cervix). As it is not ethical to do pelvic exams on girls aged 9 to 15, only blood tests were done on them.
The studies showed that both age groups developed high antibody levels after vaccination. In fact, the younger girls developed higher antibody levels than the young women. In the older age group the vaccine prevented almost 100% of pre-cancer changes in the cervix. Therefore, the researchers concluded that the vaccine would also prevent pre-cancer cervical changes for the younger girls.
