London: An Australian study has found that vaccines to protect against HPV virus, which causes cervical cancer, are working successfully after a drop in high-grade cervical abnormalities was seen.
They report that the proportion of girls aged 17 and younger with high-grade abnormalities fell by 0.38 percent – almost halving the numbers, from 0.80 percent to 0.42 percent.But there was no drop in the numbers of women with cervical abnormalities who were older than 17. This is unsurprising since the vaccine is known to be most effective if given to girls before they become sexually active.“That finding reinforces the appropriateness of the targeting of prophylactic HPV vaccines to pre-adolescent girls,” the Guardian quoted the authors as saying. The findings have been published in the Lancet medical journal. ANI
