It's not a sexual issue. I believe this is only effective when given to girls between 9 and 11, and that's the reason why they are so young.
It's effective with women up until their 20s.
The reason it's being ordered so young is that they're assuming these girls haven't had sex yet. You'd think they'd wait until it was tested on that age group before ordering it, but hey, anything to get some money.
Which is another thing that worries me, since if you've already got one of the strains the vaccine protects against, it can make it worse, and when you're 9-11, do you tell your parents if you've had sex? And yes, a few girls that young are having sex, unless things have changed since I was in sixth grade. I doubt they're going to say, "Now have you had sex?" to preteens before administering the vaccine, and if they do, it is definitely a sexual issue. An anti-STD vaccine is a sexual issue, no matter how a company tries to spin it.
They're so young because a vaccine is effective at that age? Right, newb.
Besides, the vaccine hasn't been tested long enough to know. It's all speculation and extrapolation. That's not enough to go on.
You would be wrong. It is most effective before girls are sexually active.
However, one of the side effects is painful periods so they want young girls to get the vaccine early so they don't get the painful periods.
