In a FUTURE II study conducted by scientists from northern Europe and the United States, in 2005 more than two thousand girls from Denmark, Iceland, Norway and Sweden received three doses of the Gardasil vaccine for human papillomavirus.

The first phase of the study was completed four years after vaccination, after which the effectiveness of the vaccine was tested another ten years later. For this, tissue samples from national biobanks obtained during the cervical cancer screening program were analyzed.
According to the results of the analysis, scientists found that none of the young women who received the vaccine had dysplasia, a pathological change in the cells of the cervix, which, without treatment, can lead to a malignant state.
Vaccination of young women with a tetravalent vaccine provides reliable protection against highly specific cervical dysplasia associated with HPV for 14 years. There were no signs of a weakened immune system that indicated the need to increase the dose of the drug during this period,
– said the scientists.
The FUTURE II study is incomplete and will continue for a minimum of six years to evaluate the further immunogenicity of the vaccine.

Why HPV vaccination is so important
Now the human papillomavirus is the most common infection that is sexually transmitted in adults. Some types of HPV cause dysplasia, cancer of the cervix, penis, throat and anus, as well as other rare forms of cancer. Currently, there are two types of prophylactic vaccines – Gardasil and Cervarix, which protect against the two largest pathogenic types of HPV.
The World Health Organization (WHO) has included HPV vaccination in a mandatory minimum of 10 infections, the vaccination campaign against which should be carried out free of charge and everywhere. But in Ukraine this vaccine is not included in the National vaccination calendar. You can do it yourself, but it costs more than 3,000 hryvnias per dose.
