Question
Is the fever after the baby’s chickenpox vaccination related to an unresolved pneumonia? How can parents confirm the cause of the fever?
Answer
After receiving the chickenpox vaccine, a baby may experience mild and temporary reactions such as fever, rash, and vomiting, which usually resolve on their own with rest. Severe reactions are rare. If the fever exceeds 38.5 degrees Celsius, symptomatic anti-inflammatory medication can be administered. It is recommended that parents closely observe their child and, if necessary, take them to the hospital for examination to determine the cause of the fever and administer appropriate treatment.
