When is the second dose of the varicella vaccine recommended?

The timing of the second dose of the varicella vaccine, which is crucial for ensuring effective protection against chickenpox, is recommended to be administered between the ages of 4 and 6 years. This schedule is in line with guidelines from health authorities, which suggest that the first dose is typically given between 12 to 15 months of age. The second dose, administered later, enhances immunity and helps to prevent breakthrough varicella infections.

This schedule aligns with the overall vaccination strategy aimed at providing optimal immunity to children as they enter school and are more likely to come in contact with other children. By ensuring the second dose occurs before school attendance, it fortifies the immune response at a time when exposure risks increase.
