What is the recommended age for the first dose of the varicella vaccine?

• A. At birth
• B. At 6 months
• C. At 12 to 15 months
• D. At 2 years

Answer: (C)

The recommended age for the first dose of the varicella vaccine is between 12 to 15 months. Administering the vaccine during this age range is crucial because it allows the child's immune system to adequately respond to the live attenuated virus present in the vaccine. This timing aligns with the body's natural development, ensuring that the vaccine is effective in providing immunity against varicella (chickenpox), which can be a serious illness in early childhood. Vaccinating within this timeframe also helps in establishing herd immunity within the community, protecting those who cannot be vaccinated due to medical reasons. The schedule is based on extensive research and epidemiological data, which supports that children vaccinated at this age have a significantly lower incidence of chickenpox compared to those vaccinated later or not vaccinated at all. While other suggested ages from the options might seem reasonable, they either do not align with established recommendations or could compromise the vaccine's effectiveness and the child’s health.
