That is not the primary intent. The idea is to get the girls to produce antibodies against the virus before they are sexually active, before they most likely to contract HPV. It is still not known how long the protection provided by the vaccine will last, though the CDC says "a long time." Booster inoculations might be necessary years after the initial series.
Government and the culture teaches sex has no consequences, they never teach the consequences of such a life...that is the sad part of the vaccine.. results in STD that were never even heard of decades back, abortion if you get P.G. party on....I wonder how many actual tests were done on this vaccine before it was let loose on the teen-age girls...
