Question: 5 year old needs 3rd MMR shot, is this okay?

 waterlogged5 - Fri Sep 18, 2009 7:42 pm

My five year old son (birth date 08/23/04) started kindergarten and received a letter home saying he needs another MMR immunization. Come to find out, he was given his first MMR shot 6 days too early (6 days before he turned 1 year old). He had his second MMR shot when he turned 4 years old. I have gone to the CDC website where is says the shot can not be given more then 4 days before the first birthday, so someone obviously made a mistake. I am very worried about giving him a third MMR immunization. Is this safe?

User avatar Hello,
Getting a third MMR is not a problem. Extra immunizations can be considered bonuses and if in doubt due to record keeping, it doesn't hurt to give an additional vaccine. If a child has no record of any vaccines it is safe to start the series over again completely to be sure he gets the immunity he needs.

Best wishes.
