When is the recommended time to receive the first dose of the Varicella vaccine?

• A. At birth
• B. At 12 to 15 months of age
• C. At 4 to 6 years
• D. At 18 months of age

Answer: (B)

The recommended time to receive the first dose of the Varicella vaccine is at 12 to 15 months of age. This timing aligns with the immunization schedule established by health authorities, which indicates that the Varicella vaccine is typically administered during this age range to ensure optimal immune response and protection against chickenpox. Administering the vaccine at 12 to 15 months helps to establish immunity before a child is exposed to the virus, as children are often in environments, such as daycare or school, where the potential for exposure to varicella increases. Additionally, this timing takes advantage of peak immune responsiveness in infants, maximizing the effectiveness of the vaccine. Receiving the Varicella vaccine at an earlier age, such as at birth or 18 months, is not recommended, as the immune system may still be maturing, and the effectiveness of the vaccine could be compromised. Waiting until 4 to 6 years old for the first dose instead of the recommended age could lead to a longer period of vulnerability to the disease. Thus, 12 to 15 months is the optimal time for the first dose of the Varicella vaccine to ensure that immunization is effective and timely.
