The end of
cervical cancer?
The HPV
vaccine has been much more effective than predicted, scientists have found—so
much so that it could eliminate cervical cancer altogether.
Human
papillomavirus, a sexually transmitted disease, is the leading cause of
cervical cancer.
Researchers examined 40 studies of HPV infections and
associated symptoms, covering 60 million people in 14 high-income countries
that adopted the vaccine—typically administered to girls around age 12—after
its introduction in 2006. They found that the strains of HPV most likely to
cause cervical cancer decreased by 83 percent over that period among girls ages
13 to 19, and by 66 percent among those ages 20 to 24. Cases of precancerous
cervical lesions fell by 51 percent among girls ages 15 to 19, and by 31
percent among women ages 20 to 24.
Genital warts, another potential consequence
of HPV, also fell sharply. The vaccine hasn’t been available long enough for
there to be meaningful data on its effect on cancer rates, but the researchers
expect similarly sharp declines.
Lead author Mélanie Drolet, from Laval
University in Canada, tells NBCNews.com that
the findings are “a first sign that vaccination could eventually lead to the
elimination of cervical cancer as a public health problem.”
Comment:
I remember when the vaccine came out and fundamentalist Christians objected to it arguing that it would contribute to promiscuity. It seems odd that "Christians" would rather a woman become sick and die than be protected from a disease she could contract from sexual activity. It turns out that the vaccine is saving lives and contributing to better individual and public health.
