You really won't be able to tell because after the shot, he'll be lethargic and tired... I'd say if he doesn't perk up a little by bedtime and if he's not back to 90% "normal" tomorrow morning, then call the doctor.
Call the doc if he vomits or anything like that though. But he'll be sleepy for a while... at least 4-5 hours.
I hope he perks up soon!! Poor little guy!!!
