Re: Children's vaccinations
I would caution you in citing Wikipedia as a resource about anything. I agree that it is very informative but you have to wonder about what you are reading when it could have just been edited by anyone who has an internet connection.
On season 3 of The Office, Michael Scott said, "Wikipedia is the best thing ever. Anyone in the world can write anything they want about any subject, so you know you are getting the best possible information."
I'm just sayin'.
