Hi, ds2 who is 3 years old had his pre school jabs yesterday morning. He seemed fine yesterday and woke early this morning full of beans. I was just called back to nursery as he's vomited all over the construction area 
We are due to go away for the weekend today after school. He seems fine now is sat in the bath playing with his cups, no temperature no further sick yet.
What do you think? Am I destined for a weekend of everyone throwing up due to a stomach bug or could this be a reaction to the vaccine?
Arrrrgh.
