Vaccines like polio and Tb I can see the need for in a school system. Lots of kids running around spreading who knows what germs. But STDs aren't normally transmitted by normal school activities. I would rather see this as a womens choice to take much like birth control. What if they came out with a vaccine that would make marijuana's effect null and void on your body.. Wouldn't you rather it be a personal choice and not a requirement to take?
