the vacinations don't exactly wear off ... but its good to get a booster to make sure your immune system is always upto date.
generally your suppose to grab a booster every like 5years with your general checkup
i've been innoculated against god knows what around 3times thanks to these stupid health plans i'm on. Some of the nurses i swear don't even look when they jab you they close thier eyes and hope.
Small pox is only in the dangerous virus research labs now, infact if i remember right its only in US ... but then again personally i'd be more worried if someone dropped a Cyanide bomb, 30seconds until your arterties go pop ... or a few weeks in bed with a chance to live.
Hmmm which would you be more scared of?
especially considering Cyanide or Mustard Gas and alike can be reproduced in a lab - last time i knew they couldn't achieve that with virus's yet.
