Which patient is recommended to receive the varicella vaccination?

The recommendation for the varicella vaccination emphasizes the importance of ensuring that children are adequately immunized against varicella (chickenpox) to prevent the disease and its complications. In this scenario, a 5-year-old who previously received one dose of the vaccine at 12 months of age is a candidate for the varicella vaccination booster.

The varicella vaccination series typically consists of two doses administered: the first dose is given between 12-15 months of age, and the second dose is recommended between 4-6 years of age. Since this child has received only one dose, administering the second dose is essential to achieve optimal immunity against the virus.

Children who receive one dose of the varicella vaccine by age 12 months require a booster dose to enhance their immune response, and this is typically not done before the age of 4. Therefore, this child is at the right age to receive the second dose and conform to the immunization schedule recommended by health authorities.

In contrast, the 10-month-old and the 12-year-old in the other options either fall outside the appropriate timing for the second dose or have already received the complete series of vaccinations. The 65-year-old is recommended for the shingles vaccine
