How soon after birth should the second dose of Hepatitis B be given?

Hepatitis B vaccination is a critical part of an infant's immunization schedule. The first dose is typically administered at birth. The second dose of the Hepatitis B vaccine is recommended to be given at 1 to 2 months of age, which aligns with the choice indicating 4 weeks after the first dose.

Administering the second dose at approximately 4 weeks (or 1 month) after the initial dose ensures that the infant receives adequate immunity in a timely manner. This vaccination schedule is designed to boost the infant's immune response to the Hepatitis B virus, providing protection against potential infection during the early stages of life.

The timing for the second dose is essential; it is not too early to interfere with the immune response, nor too late, which could expose the infant to unnecessary risk if they were to encounter the virus. The recommended time frame emphasizes the importance of following vaccination schedules to promote the health and safety of the child.
