How many doses of the Hepatitis A vaccine are given, and starting at what age?

  1. 3 doses starting within 24 hours after birth

  2. 2 doses starting at age 12 months

  3. 2 doses given 1 month apart

  4. 2 doses, 4 weeks apart starting at age 6 months

The correct answer is: 2 doses starting at age 12 months

The correct answer is B: 2 doses starting at age 12 months. The Hepatitis A vaccine is typically given as a 2-dose series, with the first dose administered at age 12 to 23 months, followed by the second dose 6 to 18 months later. This schedule provides optimal protection against Hepatitis A infection. Starting the vaccination series at a younger age helps ensure long-term immunity against the virus. Options A, C, and D are incorrect. Option A suggesting 3 doses starting within 24 hours after birth is not accurate, as infants do not receive the Hepatitis A vaccine right after birth. Option C states 2 doses given 1 month apart, which does not align with the recommended schedule for the Hepatitis A vaccine. Option D suggests 2 doses, 4 weeks apart starting at age 6 months; however, the standard age for initiating the Hepatitis A vaccine series is 12 months, not 6 months.
