CDC Reports Decline in Vaccination Rates as Haemophilus Influenzae Type B Resurfaces
A resurgence of Haemophilus influenzae type b (Hib), a vaccine-preventable disease, is being observed as vaccination rates among children decline. The Centers for Disease Control and Prevention (CDC) reported a slight decrease in the percentage of babies receiving the full series of Hib vaccinations, from 78.8% to 77.6% between 2019 and 2021. Hib is a highly contagious bacterial infection that primarily affects children under five years old, causing a range of illnesses from mild ear infections to severe conditions like meningitis and pneumonia. Before the vaccine's introduction in 1987, Hib affected nearly 20,000 children annually, resulting in significant morbidity and mortality. The current decline in vaccination rates is raising concerns among healthcare professionals, who are now encountering cases of Hib that they have not seen in decades.
