MIAMI, FL - SEPTEMBER 21: University of Miami pediatrician Judith L. Schaechter, M.D. (L) gives an HPV vaccination to a 13-year-old girl in her office at the Miller School of Medicine on September 21, 2011 in Miami, Florida. The vaccine for human papillomavirus, or HPV, is given to prevent a sexually transmitted infection that can cause cancer. Recently the issue of the vaccination came up during the Republican race for president when Rep. Michele Bachmann (R-MN) called the vaccine to prevent cervical cancer "dangerous" and said that it may cause mental retardation, but expert opinion in the medical field contradicts her claim. Texas Gov. Rick Perry, also a presidential contender, has taken heat from some within his party for presiding over a vaccination program in his home state. (Photo by Joe Raedle/Getty Images) less
