AAV is a virus that really hasn't been studied that much, but we are, just recently in the last few years, a number of groups in addition to our own, find it genitally. When we found this out we looked back in history and in fact there is significant historical data that AAV is actually negatively associated with cervical cancer. If you look back in history, going back to the 1960s, there is in fact evidence that Adeno-associated virus, AAV, would actually inhibit the oncogenic process caused by other viruses such as Adenoviruses. There are a whole host of Adenoviruses, some of which can cause illness. On the other hand, the Adeno-associated virus, or AAV, might actually do us some good.
Adenoviruses can cause tumours in animals.
If you infect with Adenoviruses along with AAV, you will get fewer tumours and those tumours that grow up take longer to grow up. Hence the idea that AAV is negatively associated with cervical cancer. If you have been infected with AAV you develop antibodies and you're more likely in the normal category than the cancer category. However I would say that we really haven't done enough work to truly know that exact percentage. It is believed to be a non-pathogenic virus.
