I was told that after he takes the liquid form of vax that it is possible to throw up but not likely. I would report it to your doc only because its a 'new' vax and should told. If your son didn't have the liquid then I'd take his temp and observe his behavior and see if your doc can give you more and better advise on what it might be. when the vax is in the mix its always best to consult your doc.
