Amid questions about the safety of the HPV vaccine Gardasil, one of the lead researchers for the Merck drug is speaking out about its risks, benefits and aggressive marketing. Dr. Diane Harper says young girls and their parents should receive more complete warnings before receiving the vaccine to prevent cervical cancer. Dr. Harper helped design and carry out the Phase II and Phase III safety and effectiveness studies to get Gardasil approved, and authored many of the published, scholarly papers about it. She has been a paid speaker and consultant to Merck. It's highly unusual for a researcher to publicly criticize a medicine or vaccine she helped get approved. Dr. Harper joins a number of consumer watchdogs, vaccine safety advocates, and parents who question the vaccine's risk-versus-benefit profile. She says data available for Gardasil shows that ... there is no data showing that it remains effective beyond five years. This raises questions about the CDC's recommendation that the series of shots be given to girls as young as 11-years old. If we vaccinate 11 year olds and the protection doesn't last... we've put them at harm from side effects, small but real, for no benefit," says Dr. Harper. "The benefit to public health is nothing, there is no reduction in cervical cancers, they are just postponed, unless the protection lasts for at least 15 years, and over 70% of all sexually active females of all ages are vaccinated." She also says that enough serious side effects have been reported after Gardasil use that the vaccine could prove riskier than the cervical cancer it purports to prevent. Cervical cancer is usually entirely curable when detected early through normal Pap screenings.
