What is the recommended dosing schedule for the Varicella vaccine (VARIVAX)?

• A. 1 dose only
• B. 1 dose at 15-18 months
• C. 2 doses, with the first at 12-15 months
• D. 3 doses at various intervals

Answer: (C)

The recommended dosing schedule for the Varicella vaccine, commonly known as VARIVAX, involves administering two doses. The first dose is given between 12 to 15 months of age. The second dose is typically recommended between 4 to 6 years of age, which helps to ensure that children develop full immunity against the varicella virus, responsible for chickenpox. This two-dose schedule is essential because the first dose provides primary protection, while the second dose boosts the immune response, leading to a more robust and longer-lasting immunity. Current guidelines emphasize this two-dose regimen to maximize effectiveness and to reduce the incidence of varicella disease. This is why the answer indicating two doses, starting with the first at 12-15 months, is correct.
