What Are the Consequences of Repeated BCG Vaccination?

Answer

It’s quite normal for babies to have a high fever again after receiving the BCG vaccine, and there’s no need to be overly anxious. It’s too early to give the baby symptomatic anti-inflammatory medication, as it might completely eliminate the vaccine from the baby’s body, rendering it ineffective for prevention. Guidance: If the fever is below 38.5℃, and the baby shows no other obvious discomforts, no special measures are needed. Simply ensure the baby drinks plenty of water and gets enough rest. Generally, the body temperature will return to normal within 1 to 2 days. If the baby’s temperature remains below 38.5℃ and is accompanied by severe irritability, dry heaves, or if the fever persists for 2 days with a steady increase, consider whether the baby has been infected with other pathogens during this period. In such cases, it is crucial to seek medical attention promptly.
