Question: 

My 3-month old infant just vomited approximately 1:45 after receiving the rotavirus vaccine. Will the vaccine still be effective?

Answer: 

The rotavirus vaccine should not be re-administered following vomiting or spitting up as the safety of administering a repeat dose of the rotavirus vaccine is not known. If you have further questions, we encourage you to follow up with your health care provider.
