What type of immunization is given at 16-18 years of age?

The immunization that is typically administered at 16-18 years of age is the meningococcal vaccine booster. This is particularly important because it helps provide continued protection against invasive meningococcal disease, which can be severe and lead to acute complications such as meningitis and septicemia.

During adolescence, there is an increased risk for meningococcal disease, and this booster dose is recommended, especially for those who may be entering crowded living situations, such as dormitories, or are planning to attend college. The initial dose of the meningococcal conjugate vaccine is usually given at 11-12 years of age, followed by this booster between 16-18 years to ensure adequate immunity during the high-risk years of late adolescence.

In contrast, other vaccines listed, such as the Hepatitis A, Rotavirus, and DTaP, are typically administered at different stages of childhood and infancy rather than during late adolescence. This makes the meningococcal booster the most relevant choice for immunization during the 16-18 year age range.
