i believe it's parents and educators raising their hands - and saying 'we can't do anything about it - let's deal with the consequences.' why not institute proactively and have people who already have each disease come in and speak to the class about it. i've never seen someone with aids come in. they just say - 'comdoms fix all.'
Firstly, vaccines and condoms are in completely different classes. One is associated directly with sex and they other with a disease, or virus, on associated only indirectly. I don't really know if it's a good thing to lump both together. They are clearly different to me.
Let's talk about condoms and leave vaccines aside for now. I am for teaching childern/teenagers to think for themselves. The earlier you teach them to be resposible and not overprotect them the better. They grow up to become better people who are well equiped to handle life.
There is more than enough statistics to suggest that whether we like it or not, there is a significant proportion of teenages, in developed countries such as the US and UK who are sexually active. Moreover, statistics have shown that the age at which people are becoming sexually active is steady getting younger. One could speculate what the reasons maybe. Education, mass media, less strongly bound family unit, people being more open about sex, etc.. Whatever the case maybe the prudent course for politicians and medical advisors, surely must be to say if you do have sex, and we are not encouraging you to (make that abundantly clear), but if you choose to, please, please, please use a condom.
This is the only advice that one can give because you really don't know what your teens are upto. And I'd really rather not see instances of sexually transmited disease, be it hiv or not, shooting up in the teenage population, because some silly parent went to protest saying, "no, no, no they shouldn't be having sex in the first place." Practical choices are sometimes necessary. The moral standards or society are not all the same. One could wish that they were, but you would be living in a non-existant utopia. At the end of the day, i reiterate, the only prudent course is the practical one of prevention rather than panic.
BTW, like i say I am really pro teaching teenagers to think for themselves. If a teenager reasons that abstinance a choice that the would like to make, I would fully encourage it.
