Gardasil the new vaccine discovered by an Australian doctor might be vaccinated to little girls against the sexually transmitted virus that causes cervical cancer in U.S. Gardasil protects against 70 percent of cervical cancer cases. There are many strains of Human Papillomavirus (HPV) that cause cervical cancer. There are estimated to be around 100 different types of HPV viruses, and nearly 20 million people were affected by theses viruses in the year 2005 in U.S. However, the choice to vaccinate little girls is controversial as one cannot develop HPV from casual contact at school, moreover most cervical cancers can be prevented with regular pap smear tests, which find precancerous growths that can be excised. Another problem is that the vaccination cost is as high as 360 U.S. dollars.

If every sixth grade girl in the United States were vaccinated, (there are about 2 million) it would cost 720 million dollars.
