I don't know who Dr. Mercola is, but he apparently needs to return to medical school for a refresher course. HPV has very serious ties to both
Penile and Anal Intraepithelial Neoplasia, which are both pre-cancerous lesions only caused by initial HPV infection. In fact, the growing trends in
HPV coincide directly with an increase in these forms of male cancer, so it wouldn't be to far off the mark to suggest that and HPV infection in the
oral cavity might also lead to cancer in that region. Here are the results of one study conducted with gay men coinfected with HIV:

HPV is a DNA based virus, which account for the largest amount of virus based cancerous growths in humans. This of course is not to say the RNA based
viruses like Hepititis C and Human T-cell Leukaemia virus-1 don't cause cancer, but the majority are confined to DNA viruses. In the case of HPV,
early creation of some genes known as E6 and E7 can act as a sort of modified nucleotide, which leads to protein expression, interference with
cellular control of transcription, and disturbance of the cell cycle. To understand how this process happens, please allow embellish on the science a
little. First off, normal cells function and divide under the influence of two specific genes known as Rb and p53. In particular, the Rb gene is
responsible for not allowing cellular transcription to divide a cell without making sure it has enough proteins (these proteins are known as "E2F")
for division. So we can see Rb is actually a cancer suppressor, but when a cell is infected with HPV it essentially hijacks this process and allows
its own E7 gene to bind with Rb and create a blocking effect, which thus prohibits Rb from restricting transcription. Once this starts the cell will
begin to divide at whatever rate it chooses, and of course this will lead to cancerous tumors.
The HPV vaccine, Gardasil, is not manufactured using Thimerosal (not that there is much of a risk otherwise) or live attenuated virus. In fact, there
is little risk of side effects from Gardasil because it is produced using hollow virus-like particles with capid proteins resembling HPV proteins.
There is virually no risk associated with vaccines such as these because they contain no DNA or RNA for an actual infection to be established. The
only other substances contained in this vaccine are: Amorphous Aluminum Hydroxyphosphate Sulfate Adjuvant, Sodium Chloride, L-histidine, Polysorbate,
Sodium Borate, and water. You can see details of this here:
