Human papillomavirus vaccine prevents uterus cancer
Stockholm, Oct 1 (Prensa Latina) A research on a large population endorses the effectiveness of the vaccine against human papillomavirus (HPV) to prevent cervical cancer, today shows data provided by Swedish researchers.
The HPV vaccine had proven that it prevents genital warts and pre-cancerous lesions, but although there were scientific indications, there was a lack of convincing support that it also prevents cervical cancer, according to research published in The New England Journal of Medicine.
One of the survey's authors, epidemiologist Jiayao Lei of the Karolinska Institute in Stockholm, says that this is the first time that, at the population level, it could be shown that HPV immunization protects not only against the cells changes that are the precursors of cervical cancer, but also against invasive cervical cancer.
Nearly 1.7 million women (ages 10-30) in Sweden participated in the test, where after more than a decade of monitoring, those vaccinated had a much lower risk of developing cervical cancer, especially if they received the dose before the age of 17.
Jiayao explained to the specialized magazine that girls vaccinated before age 17 reduced the risk of that type of cancer by 88 percent.
For Francesc Xavier Bosch, consultant of the Cancer Epidemiology Research Program of the Catalan Institute of Oncology, in Barcelona, I assure that this is a great success of preventive medicine.
We are left with the logistic and political question of producing enough vaccine and distributing it in time to immunize the populations, he said.
