Question

My daughter, 6 months old, received her vaccine at 11 AM on the 18th. She had a fever of 38℃ at 10 PM that night. Her temperature was 38.5℃ at midnight. I gave her warm water and wiped her down with warm water. On the morning of the 19th, her temperature was 37.2℃ at 10 AM and 38.5℃ again at 7:30 PM. Is this a reaction to the vaccine or could she have caught an infection? Additionally, she had a bath at 7 PM on the 18th after receiving the vaccine.

Answer

After your baby received the vaccine in the morning and developed a fever that night, it’s highly possible that the fever is a reaction to the vaccination, and your approach to physical cooling (cooling) was correct. However, if she continues to have recurrent fevers, it’s important to rule out other causes. I suggest checking if there’s any redness or swelling at the vaccination site. You may also want to visit the hospital for a thorough examination to rule out regional inflammation or a cold, and then proceed with targeted treatment so that your baby can quickly regain her health.
