Host: New vaccine called Gardasil for -- specifically to prevent HPV a vaccine against cancer, is that true?
Ludovico Guarini: That's actually, the statement is actually true in the sense that the papilloma virus, which is a virus that we can give each other very frequently because it's sexually transmitted virus, happens to be one of those viruses that once takes residence in the genital tract of a woman, can eventually over time develop into a form of cancer of the portion of the uterus.
If you can immunize against that cancer and therefore the virus cannot take residence, then you actually prevent - preventing the cancer and so it actually makes a lot of sense to give this vaccine to young women before they become sexually active, so that they prevent --
Host: The reason to that is they already have the virus if the vaccine doesn't work.
Ludovico Guarini: Correct, an older person then wouldn't -- once they have been exposed to that virus, the vaccine essentially has no impact.
