Final answer:
Children between 15-59 months of age who haven't had any dose of Hib vaccine should receive a single catch-up dose according to CDC recommendations. The typical schedule includes doses at 2, 4, 6, and 12-15 months. Consultation with a healthcare provider is crucial for personal health considerations.
Step-by-step explanation:
If a child is between 15-59 months of age and hasn't had a dose of Hib (Haemophilus influenzae type b) vaccine, the Centers for Disease Control and Prevention (CDC) recommends that the child receives a single catch-up dose of the vaccine. This is due to the serious illnesses caused by H. influenzae such as meningitis, which can occur in young children who are not yet fully immune.
The recommended immunization schedule typically includes vaccinations at 2, 4, and 6 months of age with a final booster dose at 12 to 15 months of age. It's important to note that the administration of vaccines can vary based on a child's health history and the specific guidance of their healthcare provider. Vaccinations are a vital part of keeping children healthy by preventing serious diseases. Without the Hib vaccine children are at risk of developing dangerous infections caused by Haemophilus influenzae.
