just now, i had a tutorial about vaccination in children, a topic that i am very familiar about and something that i can say it out loud with full conviction if asked. but as much i would like to believe that i was well prepared, the sad truth was what i know is practically next to nothing if compared to the knowledge that i have yet to learn. so, what more can i say? the more reading i do, the more i realize that ... what i have is pretty much inadequate.
