Question
What are the common adverse reactions that may occur after a newborn is vaccinated with the BCG vaccine?
Answer
After a newborn is vaccinated with the BCG vaccine, common side effects may include local hardness, swelling, and fever. Additionally, if the newborn develops symptoms of a cold and fever after vaccination, it is recommended to defer vaccination to avoid affecting the immune effect and exacerbating the vaccine side effects. Typically, delaying the vaccination for a few days is acceptable and will not affect the immune effect. Parents should closely monitor their child’s condition and seek medical assistance when necessary.
