When should an infant receive their first dose of the hepatitis B vaccine?

• A. At 2 months
• B. At 6 months
• C. At birth
• D. At 1 year

Answer: (C)

Infants should receive their first dose of the hepatitis B vaccine at birth to provide them with crucial early protection against the virus, which can lead to serious liver conditions. Administering the vaccine at this stage is essential because it helps to prevent mother-to-infant transmission, especially if the mother is a carrier of the hepatitis B virus. The early vaccination also contributes to the establishment of immunity ahead of potential exposure to the virus as the infant grows. Following this initial dose, additional doses are recommended at 1-2 months and 6 months of age to ensure complete vaccine efficacy and long-lasting immunity. Timely vaccination according to the recommended schedule is key in preventing hepatitis B in children.
