My Baby Has a Fever on Vaccine Day – What Should I Do?

Is Fever After Vaccination Normal?
Yes—mild fever after vaccination is a sign that your baby’s immune system is responding to the vaccine. It’s not only expected, it’s a good thing. Fever means the body is building protection against serious infections like diphtheria, pertussis, polio, and pneumonia.
Most babies experience low-grade fever (99–101°F) within 24 hours of receiving shots, especially after hexavalent vaccines, PCV, or rotavirus vaccines.
What You Can Do at Home
Here’s how to comfort your baby and manage post-vaccine fever safely:
🍼 Keep your baby well-hydrated with breastmilk or formula
🌡️ Monitor temperature regularly using a digital thermometer
👕 Dress your baby in light, breathable clothes
🛏️ Allow extra rest and avoid overstimulation
💧 Use a lukewarm sponge bath if fever crosses 101°F
💊 Administer infant paracetamol only if prescribed by your pediatrician
If you’ve opted for a painless vaccine, fever may be milder or absent—but even painless options like Infanrix Hexa or HexaSim can trigger a mild immune response.
When to Call Your Pediatrician
While mild fever is normal, watch for these red flags:
Symptom | Action Needed |
---|---|
Fever > 102°F (under 3 months) | Call your pediatrician |
Fever lasting > 72 hours | Medical evaluation advised |
Vomiting or diarrhea | Monitor hydration, seek help |
Extreme drowsiness or irritability | Pediatric consultation |
Refusal to feed or swallow | Immediate attention needed |
