Yes, some baby vaccines can cause vomiting, but this is not a common side effect and is usually mild and short-lived.

Most common situation:

  • Rotavirus vaccine (oral drops): Within 1 week after this vaccine, mild vomiting, diarrhea, or fussiness can occur. This is a natural reflection of the vaccine working in the intestines and usually resolves within 1-2 days.
  • Other injected vaccines (five-in-one combination, pneumococcal, BCG, etc.): Vomiting is not a common side effect from these. More commonly seen are fever, fussiness, injection site redness/swelling.

When to be concerned:

If vomiting starts immediately after vaccination (within 30-60 minutes) or is severe (projectile after each feeding), accompanied by high fever (≥38°C), rash, extreme sleepiness, or no wet diapers for 6+ hours — this suggests a cause other than the vaccine (infection, reflux episode) and you should consult a pediatrician on the same day.

In short: Mild, occasional vomiting that resolves on its own after vaccination is not unusual. But if it's continuous, severe, or accompanied by other symptoms, see a specialist.
