Hepatitis B is indicated for which age group?

Hepatitis B vaccination is recommended for individuals starting at birth and continuing throughout life, making it essential for all infants and older. Administering the vaccine to newborns is particularly crucial since hepatitis B can be transmitted from an infected mother to her child during childbirth. The vaccine schedule is designed to provide immunity at an early age, typically with the first dose given within 24 hours of birth.

This comprehensive vaccination guideline ensures that as many individuals as possible receive protection against hepatitis B from the onset of their lives and reduces the risk of chronic infection and transmission. Thus, recognizing this begins at birth solidifies the rationale behind choosing the specific age group indicated in the correct answer.
