HPV vaccine linked to reduced cervical abnormalities

The HPV, or human papilloma vaccine, is only recommended in the U.S. to prevent cervical cancer. But in some countries it is required. In Australia, a population wide vaccination program was introduced in 2007 for women 12 to 26.

Now a new study in the Lancet medical journal finds the vaccine may be linked to reduced cervical abnormalities.

Researchers say, since that program started, the rate of cervical abnormalities, or HGA, was cut in half in women under 18. There was no drop in rates in older women.

The CDC warns these results should be viewed with caution. Doctors add, it will take decades to show a true reduction in cervical cancer.
