normal reaction??

Ds had his 4 month immunisations yesterday, we have delayed him having any till he was over 6 months, so now we are on a catch up schedule.
anyway, after the injections ( a 5in one and pneumovax, one in each leg, he is too old for the rotateq) he cried for a bit and was generally unhappy, came home had a sleep, then woke up, still tired, very whingey, bed time comes around and he starts SCREAMING, now for my ds this is unusual, he is not a screamer, never has been, he screamed for over an hour and was unconsolable, we dosed him up with panadol, didnt make a difference, after another hour or so, he fell asleep and was restless and crying in his sleep. didnt have the usual 3 wakeups though.
this morning he seems happy enough, but halfway thru giving him his bfast he started spewing, everywhere! about 3 times, his morning feed and all his cereal.
I cleaned him up and gave him some water then he fell asleep.

I know most kids have reactions to the injectons, but is this normal?? cause its really not normal for my never spewey or screamy baby??

the screamy bit yes but i havent ever heard of a reaction of vomitting. (unless its with the rotavirus one vaccine).
