Question
If my child develops a fever at 4 PM after a morning vaccination, can I give them medicine or a shot?
Answer
Adverse reactions to vaccinations typically last for 1-2 days and then improve. Common symptoms include slight fever, rash, decreased appetite, hardness at the injection site, irritability, and sleepiness—though in very rare cases, some babies may experience fainting or seizures. It is best to stay in the hospital for half an hour after receiving the vaccine for observation. Upon returning home, reduce activity and rest well for 1-2 days. It is recommended to use physical methods to reduce fever, as there are many factors that can affect a child’s respiratory system. If a child is diagnosed with a respiratory infection, parents should cooperate with the doctor for immediate treatment, including gastrointestinal decompression, and develop good hygiene habits. Parents should also be cautious not to foster picky eating habits in their children and ensure a balanced diet.
