But when they first came out with the vaccine wasn't the message that if you take the vaccine, you'll be immune to the virus & we'll thus make the virus extinct? Ala, measles, polio, small pox, etc., etc. That was certainly my understanding (I realize I put that in terrible layman's terms. Lol.)
But if that was in fact the original message, was it an over-simplification? Or perhaps wishful thinking from the beginning? Or was the vaccine simply not as effective as originally hoped?
And I'll ask here because it sounds like you have a pretty good idea of what you're talking about: how is it we had effective vaccinations for measles, polio, small pox, etc., but not for the flu or the "common cold?" What's the difference?
