At what age is the varicella (chicken pox) vaccine recommended?

The varicella vaccine, which protects against chicken pox, is recommended to be given to children starting at 12 months of age. The vaccination schedule typically includes two doses: the first dose is given between 12 to 15 months of age, and the second dose is administered between 4 to 6 years of age. This vaccination is crucial for preventing chicken pox, which is a highly contagious viral infection.

As a component of routine childhood vaccination schedules, the recommendation for vaccination at 12 months and older ensures that children develop immunity at a young age, before they are likely to be exposed to the virus. Consequently, children are less likely to contract chicken pox, reducing the overall incidence of the disease in the community.

In light of this information, the age range provided in the answer option (A) does not align with the current vaccination guidelines. Therefore, focus on the correct age range for the initiation of the varicella vaccine, which is from 12 months and older.
