Patient's question:
The baby is 30 days old and has a slight fever. Vaccination is not possible, and it's almost New Year's, so it will take 20 days to get vaccinated. There is no significant impact.Past treatment history and effectiveness: None
Desired help: The baby can no longer get the flu vaccine. I would like to ask if delaying the vaccination by 20 days after the baby is 30 days old will have any adverse effects.
Doctor's answer:
When the child was 30 days old, the vaccine administered was the third dose of the hepatitis B vaccine. It can be postponed, but it should not be delayed by more than 15 days, otherwise it may interfere with the concentration of antibodies. However, the child has a cold and it's the Chinese New Year, so there's no choice but to wait 20 days before vaccination. After the second dose of the hepatitis B vaccine, wait two months—when the child is eight months old—to have their blood tested for hepatitis B antibodies. If the level is sufficient, there's no issue. If it's not enough, a booster dose of the hepatitis B vaccine may be administered if necessary.
