Immunization can prevent long-term effects of meningococcal disease, such as hearing loss and psychological problems

A systematic literature review of studies of the long-term effects of invasive meningococcal disease in high-income countries found that children who survived the disease had a greater incidence of hearing loss and psychological problems, including attention-deficit/hyperactivity disorder (ADHD) than control groups or the general population. In addition, they had increased odds of death – one study showed more than a 25% greater mortality rate in this population than did the general public up to 30 years after having the disease.

Immunization with PCV reduced antibiotic prescriptions for children and slowed antibiotic resistance

In Iceland, a study of all children born over an 11-year period, before and after the introduction of pneumococcal conjugate vaccine (PCV) into the national immunization program, found a 6% decrease in all antibiotic prescriptions for children during their first four years of life and a 22% reduction in prescriptions for otitis media after the vaccine was introduced. Thus, in addition to reducing the burden of pneumococcal disease, PCV may also slow the spread of antibiotic resistance.
