With every drug, there is a risk/benefit assessment. In the case of Vioxx, it turned out that there was a small increased risk of a cardiovascular event among those taking the drug, and the decision was made that this risk outweighed the benefits. With other drugs, the same level of risk might be deemed acceptable with regard to the benefit.
In the case of Gardasil, the risk is no higher or different than the risk for any other vaccine. The risk of a sore arm is judged acceptable in view of the benefit of decreased disease and healthcare costs.
I hardly consider 250,000 to 1 million new cases of cervical dysplasia per year a "small group of girls." In terms of health care costs, long-term health risks, and risks to fertility, that's a huge number. Personally, I think it's atrocious that parents would expose their children to painful medical procedures and permanent damage to their reproductive organs because of unfounded rumors and fears.
Since you seem to think that the only driving factor is profit (as if profiting by providing a life-saving service is somehow immoral), keep in mind that it is far more profitable to not vaccinate, and let women develop the disease. A diagnostic colposcopy with biopsy would cost roughly $1000. The treatment method and price depend on the biopsy results, but can range up into several thousand dollars. If the disease progresses to metastatic cancer, then the prices rise even more. In contrast, the Gardasil vaccine series costs $360 plus doctor fees. For less than the cost of a colposcopy, the need for one can be decreased by about 70%. Price isn't the only consideration--the colposcopy and subsequent treatment are incredibly painful.
