Is it really necessary to get the hepatitis A and Typhoid needles done if your going to Cancun, or would I be overly cautious in doing so..
Typhoid I don't know how important it is for Cancun, Hep A or HIB (Hep A/B which is what they'll give you) is generally something worth just having like tetnus. I got all mine done 3 years ago, none of them compare to the Gardasil one they've been giving to girls here, that stuff hurts more then anything I've ever had, you guys were lucky to not have to have it!!
Have you ever gotten TB vaccine? That's the worst. The area around the insretion point gets really gross a few weeks after the shot. You can easily tell if someone had TB shot from the big circlar scar on their upper arm.
