Does baby vaccine cause diarrhea — is this normal, or should we see a specialist?

The real reply from the in-app AI advisor

Mild diarrhea after vaccination is possible, this is usually a normal side effect that passes on its own within 1-2 days. Especially after live vaccines like rotavirus — your baby's immune system is responding to the vaccine and the digestive system can be slightly affected.

What's considered normal: 3-4 loose stools a day but without blood, no fever or mild fever, baby's overall condition is good and they're still nursing or feeding.

When to consult a specialist:

  • If diarrhea lasts longer than 48 hours
  • If there's blood or mucus (like phlegm) in stool
  • If baby has fever of 38°C or higher
  • If diapers stay dry for longer than 8 hours (sign of dehydration)
  • If baby seems lethargic, listless, or crying constantly

If any of these signs appear or you're not comfortable, consulting your pediatrician is the right thing to do.
