Study shows continued success for new HPV vaccine against virus responsible for cervical cancer
...three shots of a new HPV vaccine marketed by Merck under the name Gardasil could make the difference in preventing cervical cancer. The vaccine targets HPV types 16 and 18, which cause about 70 percent of all cases of cervical cancer. It also targets HPV types 6 and 11, which together cause about 90 perc...Dealing deadly cancers a knockout punch
