Since 2017, children under the age of 15 need 2 doses of the vaccine against HPV – the human papilloma virus. New research from Boston Medical Center, published in the renowned STD Journal, is the first scientific publication to demonstrate clinical evidence supporting the recommendations of health organizations around the world for two doses of the HPV vaccine to prevent genital warts. The study included almost 400,000 US girls, in which the incidence of genital warts, one of the symptoms of human papillomavirus infection, was examined. The scientists found that receiving two or three doses of the vaccine provided strong and adequate protection, while receiving one or zero vaccines left the body highly susceptible to infection. The vaccine also prevents other health problems caused by the infection – cancers of the cervix, labia, vagina, anus, mouth and throat, and penile cancer in boys. The study confirms the recommendations of the World Health Organization to vaccinate both girls and boys, who are considered the reservoir of the disease, which is widespread throughout the world.

Although warts can be surgically removed, they are only symptoms of HPV infection, which, in addition to the listed cancers, can also cause infertility. The virus is one of the most prevalent in the human population, with 12% of women worldwide believed to be infected. In the United States, nearly 27% of women between the ages of 14 and 59 also carry at least one type of HPV.
