Question
The baby is 30 days old and has a slight fever. Can’t get vaccinated, and it’s almost New Year’s. I’ll have to wait 20 days until I can get it done. Will there be any effects?
Answer
The vaccine administered to the baby at 30 days is the third dose of the hepatitis B vaccine. It can be postponed, but it should not be delayed for less than 15 days, otherwise, it may interfere with the antibody concentration. However, since the baby has a cold and it’s New Year’s time, there’s no choice but to wait 20 days before vaccination. After that, two months after the completion of the second dose of the hepatitis B vaccine, which is when the baby is eight months old, we should check the baby’s hepatitis B antibody levels through a blood test. If there are enough antibodies, it’s fine. If not, a booster dose of the hepatitis B vaccine may be necessary.
