Vaccines, fever, & fussiness

I live in Guam so we’re a day ahead.

Thursday around 130-2pm my son had is 8week vaccines. Today is Sunday (night) & he’s still having sporadic temperatures of 99.0degrees and/or feeling sorta clammy/sweaty.. he’s also been extremely grumpy. Is this normal???? From what I’ve read, this isn’t suppose to last this long.
