I can't say for sure it is good or bad...anything new makes me nervous...but it is tragic that the reason I guess they are giving it to 12 year olds is that is the latest they can expect them to be virgins and the vaccine has to be given before for some reason supposedly..I haven't really followed it. Yikes. That says so much about us as a country that we can't or won't both protect our girls and protect society from their behavior and enforce what should be some basic rules of behavior, which means chaperoning them and the boys every minute just about at least in mixed company at least till they are 16 or so...there just should not be opportunities for children to get pregnant or the social enabling of it and that is what we do. I am not talking about 17 year-olds hear, or 16...but 11, 12, 13, 14..what the hell is going on and why aren't people more upset? You must chaperone young teens period. There is nothing else that works other than separating them or bringing back the nuns...mg
