Research published by the Journal of Adolescent Health demonstrates a reality that Big Pharmas Merck & Co. ($MRK) and GlaxoSmithKline ($GSK) have experienced for years: There's an abundance of misinformation circulating about HPV vaccines.

In some cases, the misleading or incomplete sites highlighted safety concerns with the vaccines and contended that the vaccines encourage sexual activity, two misperceptions that have hampered uptake and dragged on sales in the vaccine category for some time.
