Hi
Welcome to the MedHelp forum!
The safety and side effects of H1N1 vaccine in less than one year olds is not studied in detail. Hence if your little one had vomiting and fainted, please rush to ER or meet her pediatrician ASAP. Please let me know if there is any thing else and do keep me posted. Take care!
Don't assume anything with one this young, call her pediatrician about this.
