German scientist Harald zur Hausen engaged in cancer research broke medical dogma. He found that cervical cancer can cause human papilloma viruses, so-called. HPV infection.
Sexually transmitted HPV virus types 16 and 18 cause 70 percent of cervical cancer in the world. Nobel Committee convinced and practical use of the discovery – the development of a vaccine against cervical cancer. This vaccine is used for prevention before the onset of the second most common type of cancer in women. Prevents the development of infections and thus cancer.
Vaccine is very effective, but due to the small coverage virus strains will not protect completely. In the genitals occurs thirty HPV viruses. Most of them are relatively harmless and immunity of the body to cope with them. The vaccine, which is offered on the Czech market, has voted against the perpetrators of cervical cancer, HPV 16 and 18, as well as against viruses that cause genital warts, HPV 6 and 11.
There is still 30 percent of the tumors induced by viral infection, in particular HPV 31 and 45, against which the vaccine was not present. Also against them, but the woman could resist. It is necessary to periodically (at least annually) to undergo screening examinations by a gynecologist. Female doctor performs smear test to see whether the cervical cells changed as a result of HPV infection.
In the Czech Republic we are still talking about the greatest benefits of vaccination for girls aged 11 to 14 years. Vaccination should in any case be carried out before the first sexual intercourse. After three doses of the vaccine (a total of about ten thousand) girls are totally protected against viruses riskiest. Revaccination is recommended soon after 10 years, it is possible that the effect will be lifelong. In women who are already met, and human papillomavirus infection developed, the vaccine is not very effective.
Great risk for developing cancer is the early start of sexual life, partner rotation, other sexually transmitted infections and the overall state of immunity. Smaller role of smoking and oral contraceptive use. In the Czech Republic, cervical cancer annually 400 sick women.
However, the situation improves. At the end of last year in the Czech Republic against the formation of cancer initiated vaccination. Women of them are very interested. Men are not only carriers of the infection, but they are threatened. Annually appears in 40 cases of cancer of the penis. Also, men can protect themselves against infection by vaccination.
This year’s Nobel Prize in medicine from a Stockholm also took French virologists Luc Montagnier and his colleague Françoise Barré-Sinoussi. They had gotten the other half of the price for their discovery of the HIV virus that causes Aids.
