My 3yo had his first flu nasal vaccine this morning and was sick at lunch time and also while having his dinner tonight. He already had a bit of a cold and cough which I put down to him being sick at lunch because he was coughing so much it just came back up. Then he seemed himself again after just a bit sniffly etc. is it normal for the flu vaccine to make children sick tho? Bit worried with everything in the news at the minute and I've never had one myself! I know it can give you some cold/flu symptoms but vomiting?
