Day after vaccines

Nichole • Mommy to an 👼🏻 baby and to our 🌈 baby boy’s, Charlie 6-12-19 💙💙 Emmett 5-18-21 💙💙

Baby got his first vaccines yesterday. He ran a fever at night. Today he cries to eat, but can’t eat or spits it all back up. Is this normal after vaccines?? Or should I call the doctor? He has kept down maybe 2oz all day so far.
