After receiving the pentavalent vaccine, if the baby is drowsy, should they be woken up?

　　"Quintuple vaccine" usually refers to the combination vaccine. Whether a child should be woken up after becoming drowsy following the quintuple vaccine depends on the specific circumstances. If the drowsiness is brief, generally there is no need to wake the child; however, if it lasts a long time, waking the child is necessary. If discomfort symptoms occur, prompt medical attention is recommended, and treatment should be conducted under a doctor's guidance. Detailed analysis is as follows:

　　The quintuple vaccine is a combination vaccine that protects against diphtheria, pertussis (whooping cough), tetanus, poliomyelitis (polio), and diseases caused by Haemophilus influenzae type B. After vaccination, some children may experience drowsiness, which is typically a normal immune response triggered by the vaccine stimulating the body. If the child is only mildly drowsy for a short period and remains in good spirits, there is generally no need to wake them—allowing adequate rest is sufficient.

　　If the drowsiness persists for an extended period—more than 72 hours without improvement—or is accompanied by severe symptoms such as high fever, seizures, or difficulty breathing, the child should be woken promptly. Observe their mental status and seek immediate medical evaluation and treatment.

　　After vaccination, children should get appropriate rest and avoid strenuous activities and excessive fatigue. At the same time, parents should provide a quiet and comfortable resting environment to support the child’s recovery and overall health.
