What is the vaccination schedule for the Hepatitis A vaccine?

• A. One dose at 12 months
• B. Two doses at 12-24 months
• C. Three doses within the first year
• D. Four doses at any age

Answer: (B)

The correct vaccination schedule for the Hepatitis A vaccine involves two doses administered to individuals, typically starting between the ages of 12 to 24 months. The first dose is given at the age of one year, followed by a second dose six to twelve months after the first. This two-dose series effectively builds and maintains immunity against Hepatitis A, ensuring optimal protection. The two-dose regimen is based on extensive research and clinical guidelines that establish the best practices for immunization against this viral infection. This approach has proven to provide long-lasting immunity, reducing the risk of future infections in vaccinated individuals. Other schedules, such as a single dose at just 12 months, do not provide the optimal level of protection, as the body requires that second dose to fully establish a robust immune response. Similarly, three or four doses are not part of the recommended guidelines for Hepatitis A vaccination, which focuses on the two-dose series for effective prevention.
