Hi there and thanks for using Petco Pet Education Center, formerly Petcoach! Lethargy is a common side effect from vaccinations-however on the other spectrum, a few patients do experience a bit of hyperexcitability as you have described. Our pets are just like us, each one is different. I would suggest monitoring his behavior over the next 24 hours-if these are the only side effects you notice it is likely he is fine. Is should subside within the next couple of days.
