There Is a Controversy Over Pre-Teen Girls Receiving the HPV

There is a controversy over pre-teen girls receiving the HPV vaccine.Many parents think that giving this vaccine condones sexual activity at a young age.On the other hand, there are parents who do not want their kids to pick up STIs.Why is the vaccine recommended for 11-12 year old girls? Why not give the vaccine to young adult women who are just becoming sexually active?

A) The vaccine is cheaper for young girls since the dosage of virus in the vaccine is far less than that given for older women.
B) The immune system is strongest in pre-teen girls, so it is best to give the vaccine very early in life.
C) Once the young woman becomes infected with HPV, the virus gets into cells.It is then too late to vaccinate.
D) Very young women tend to get cancer from HPV, whereas women who are older get warts from HPV.
