live attenuated guys

salam.

i've just read about vaccines and live attenuated cultures of viruses

and thought:

if the virus is a guy,

his ability to cause a disease and his ability to replicate must be removed from him

so~

his ability to cause a disease must be like his weapon...

and his ability to replicate must be his.................

ok, i don't have to tell, coz you've guessed it alright

:P
