In the context of immunization for a 13-year-old who has not received any previous vaccinations, the Haemophilus influenzae type b (HiB) vaccine would typically not be included in the catch-up schedule at this age. The HiB vaccine is primarily recommended for children under 5 years old, with the series usually completed by the time a child reaches 18 months old.

By age 13, the need for HiB vaccination diminishes significantly because the target population for this vaccine is younger children, whose immune systems are still developing, and they are at a higher risk of severe disease from HiB infections. Children over this age are generally considered to have lower risk, and vaccination efforts focus on other immunizations that are critical for adolescents, such as Tetanus, MMR, and Hepatitis B.

In contrast, Tetanus, MMR (measles, mumps, rubella), and Hepatitis B are recommended as part of the immunization schedule for adolescents and are included in catch-up vaccination protocols. Therefore, the HiB vaccine does not fit into the vaccination needs for a 13-year-old in terms of catch-up schedules.
