Side effects of 4th month vaccination on baby, please share it

Si

My baby girl is 4 months old and she got her vaccination a day before and her appetite has reduced and she has puking feeling.

She doesn’t take epb bottle too completly and she rejects Also breast fed too.

It all started after a day of giving her vaccination.

I’m not sure if this is normal or is this because of her teething .

Your answers will help me figure out what’s happening in my lil girls body
