To follow up on the NL Right To Life group's weak-ass objection that the HPV vaccine may be premature, MSNBC reported yesterday that Gardasil partially blocks even more strains of the virus than previously thought.
There are more than 60 strains of the HPV virus. About 15 are thought to cause cervical cancer; Gardasil protects against 12 of those, plus another two that cause genital warts but not cancer.
Two strains cause 70 percent of cervical cancer. Merck studies following 17,600 young women for three years found the vaccine to be 99 percent effective in blocking those strains.
New analysis of that data shows the vaccine reduced incidence of HPV-caused precancerous lesions by nearly two-thirds for the three next most common HPV strains in North America. While those three strains are less common elsewhere, together they cause about 11 percent of cervical cancer worldwide.
“There’s the potential for an additional 30,000 to 40,000 cancer cases being prevented each year,” mostly in developing countries, based on preliminary estimates and widespread vaccination in those regions, said Dr. Eliav Barr, head of Merck’s research on infectious disease and vaccines.
There are 9,710 new cases of cervical cancer and 3,700 deaths in the U.S. each year. Worldwide, there are nearly 500,000 new cases and 233,000 deaths a year.
No more delay, no more "please package the vaccine with a particular moral stance on sexuality"... just save women's lives.
