rotateq vaccine

soI brought my 3-month old daughter today to her pedia and she was given the vaccine for rotavirus. it's oral so the baby had to swallow it. after swallowing the whole amount, she vomited. so i thought, oh my,it all went to waste. it was sooo expensive! the pediadidn't give her another dose. she said it's ok,but i think she should have given some more... what you ladies think? any experiencelike this?
