The first major study of an experimental vaccine to prevent cervical cancer found it was 100 percent effective

No shit?

I’d like to see a study that wasn’t done by the maker of the vaccine, but if this turns out to be true, it’s hellacool:

The first major study of an experimental vaccine to prevent cervical cancer found it was 100 percent effective, in the short term, at blocking the disease and lesions likely to turn cancerous, drug maker Merck & Co. said.

Gardasil, a genetically engineered vaccine, blocks infection with two of the 100-plus types of human papilloma virus, HPV 16 and 18. The two sexually transmitted viruses together cause about 70 percent of cervical cancers.
