Patient's question:
The baby got the 13-valent pneumococcal vaccine yesterday and had a fever, with a high of 38.3°C. This morning, the fever is gone, but in the evening, he kept tilting his head back. What could be the reason?Doctor's answer:
Some babies may experience low-grade fever the night after vaccination or within 1-2 days, sometimes even developing into fever or a cold. This is an adverse reaction as the vaccine interacts with the body's immune system. The feverish temperature is usually below 38.5°C and lasts for 1-2 days. The baby's resistance will improve, so it's important to give them more fluids and ensure they get adequate rest.
