Conspiracy Theory: Government Funded Mass Inoculations

I've always feared the needle specially during my childhood days those free inoculations sponsored by the government.Now that i think about it we make ourselves vulnerable to become government test subjects for bacteria, viruses, new drugs or new vaccines, disguised as standard procedure vaccination. Not only that maybe the government can also give unsuspecting children random sterilization drugs to curb population growth. I am not saying this is happening. I am saying that children are vulnerable to that in case the government decides to do
that after all to the government a person usually is just a statistic. The military however has a higher possibility of using unsuspecting soldiers as test subjects for performance enhancing drugs with some unknown side effects that maybe its a contributing factor to a returning soldier's physical and psychological health. Anyway these are just theories. =)
