The World Health Organization approbed the second vaccine (Cervarix) against cervical cancer. The vaccine is the result of many years of research on the cause of this type of cancer. It is now accepted that a virus, papilloma virus, causes the transformation of cells that leads to cancer. The virus is sexually transmitted from men to women.
Cervical cancer is perhaps the most important type of cancer in women of the third world. It causes the death of 280,000 women, 80 % in the third world. While the first world has reduced deaths by early diagnosis (Pap tests) and treatment, such facilities are not available in poorer countries and the vaccine, if it can be obtained at a lower price, offers great hope for women around the world. The idea is to vaccinate all girls at the age of puberty.
