Fever after shots

Ka

My girl had her 4 month check up yesterday. She will be 5 months next week. She got her shots yesterday and we woke up this morning and she has a fever of 102.3. I gave her Tylenol that she spit out most of and I called her doctor but they didn't seem overly concerned and kind of brushed my concerns off. They said take her temp in a half hour and then more Tylenol at noon. She didn't eat much this morning, but did spit up quite a bit. She seems okay behavior wise. But I'm jusg wondering if I should be concerned? She didn't have any issues with her last round of shots. I'm a first time mom and I trust her doctor but I guess I just don't want to be doing the wrong thing with a fever on the higher end. I guess I'm jusg looking for reassurance or any tips to help bring her fever down in the mean time.
