Question:

My 15-month-old baby had a fever ranging from 37.8°C to 39.8°C from Wednesday morning to Friday night. There were no other symptoms, so I monitored the situation while giving fever reducers. By Saturday, the fever was completely gone, but a rash appeared in the evening, which makes me think it was roseola.


We were supposed to get the DTaP vaccine this week and the inactivated Japanese encephalitis vaccine next week. These were already delayed by a month due to a cold. Now that my baby has gone through this fever and rash, when should we reschedule the DTaP and Japanese encephalitis vaccines? The baby's overall condition and energy levels are currently good.


Answer:

Hello! It does sound like your baby went through a typical case of roseola, which classically presents with 3 to 4 days of high fever followed by a rash just as the temperature drops.


Vaccination Timing

If your child's condition is good, vaccinations can generally resume one week after recovering from roseola.

  • DTaP: This can be scheduled roughly one week after the rash first appeared.

  • Japanese Encephalitis: This can be administered one week after the DTaP vaccine.


Checklist Before Vaccination

Before proceeding with the shots, please ensure the following:

  • It has been at least 48 hours since the fever completely resolved.

  • The rash has mostly faded or disappeared.

  • Your baby's appetite and activity levels have returned to normal.

  • There are no symptoms of any other underlying infections.


Additional Notes

While roseola is a viral infection, it is safe to proceed with vaccinations once the child has fully recovered and their immune system has normalized. Try not to worry too much about the vaccines being delayed by a month. The absolute most important factor is ensuring your child is healthy at the time of vaccination.


When you visit your pediatrician, please inform them that your baby recently had a suspected case of roseola. The doctor will perform a physical examination to confirm your baby is fully ready before proceeding with the vaccinations. I am glad to hear your little one is recovering well!
