Question: 

Hi, My son spat out most (about 3/4) of the rotavirus vaccine today. Will he still be able to build immunity from the small amount he got? Thank you,

Answer: 

We recommend that you contact your local public health unit and ask to speak with a public health nurse.  A public health nurse can gather the additional information from you that is needed to better answer your question. 

The rotavirus vaccine should not be re-administered following spitting up as the safety of administering a repeat dose of the rotavirus vaccine is not known.
