Patient's question:
Doctor, hello. My baby was born on August 23rd, and had jaundice during the postpartum period. I didn't get the second dose of the hepatitis B vaccine. During this time, the baby had a cough, bronchitis, and was hospitalized. After recovering, the baby was affected by the elder sibling's cold. It wasn't until November 11th (when the baby was two and a half months old) that we went for vaccinations. The doctor said the delay was too long, and the first dose was wasted. Today's shot counts as the first dose, and the second dose will be given on December 11th. I would like to ask if this will affect the baby? What is the maximum delay allowed for the first and second doses? If delayed by two and a half months, does the first dose become useless? I don't want to give the baby the shot. IfDoctor's answer:
According to your description, the normal vaccination schedule for your baby to receive the hepatitis B vaccine is the first shot within 24 hours of birth, the second shot at one month, and the third shot at six months. Advice: It's okay if your baby's second shot is slightly delayed, as it generally does not affect the antibody effect. The third shot should be administered at six months as scheduled, and there is no need for a fourth shot. Wishing your baby healthy growth.
