I asked this question on another thread, and it may have already been answered somewhere, but I am having a hard time finding the answer. At what point (age) is the MMR considered safe? My son is 4 1/2 years old and has received all of his vaccines except for this one. He is already enrolled in an early pre-k program with help for speech/language delays/articulation errors. I have held off on this vaccine mainly because of the autism concern. If my son is already showing speech delays, could giving him the MMR shot push him over the edge??? That is the question that I asked his pediatrician, and the pediatrician said that he truly doesn't believe that MMR causes autism but that we can delay the shot as needed. My concern is that he will be starting kindergarten next fall. We went and got a religious exemption due to the way the MMR and Varicella vaccines are made (he already received the first dose of varicella at 15 months before we learned about how it was made, but has not received the second dose which will also be required before kindergarten enrollment), but now I'm reading that you can't be religiously exempt for just a couple of shots - it's all or none. So, if we are forced into complying, do you think that at 4 1/2 my son is past the "dangerous" time to receive this shot? Any advice is greatly appreciated!!!
