The mistakes you’re posting have already been corrected by myself and paper-machine over in this branch of the thread.
Your “correction” is that the purpose of the vaccination is not herd immunity, but individual and personal benefit—but the claim justifying compulsory and/or free vaccination is always herd immunity. If no substantial externality, no justification for compulsion and/or subsidy.
In fact, of course, the reason for compulsory HPV vaccination is to avoid stigmatization. If girls get to individually choose whether they want a vaccination against a sexually transmitted disease, those who so choose might be stigmatized.
