Meningitis is a serious condition that can be life-threatening. Patients with this neurological disorder have an inflammation of the meninges, which are the membranes that cover the brain and spinal cord.
Viral meningitis is the most common type of the disease and is usually non-lethal, according to the National Institute of Neurological Disorders and Stroke. Bacterial meningitis is potential fatal and several vaccines are available for specific types.
Haemophilus Influenzae Type B (Hib) Vaccine
Before the introduction of the vaccine, haemophilus meningitis was the most common type of bacterial meningitis, noted the National Institute of Neurological Disorders and Stroke. MedlinePlus added that currently, this type of bacterial meningitis occurs in less than 2 out of every 100,000 children and in 5 to 10 percent of adults.
Caused by the bacterium Haemophilus influenza, haemophilus meningitis can cause a severe headache, mental status changes, sensitivity to light, nausea and vomiting. The Hib vaccine is part of the regular schedule of vaccines for children, which starts at about age 2 months.
The MayoClinic.com noted that some adults should also get the vaccine if they have not previously, including adults with AIDS, sickle cell disease or people without a spleen.
Pneumococcal Conjugate Vaccine (PCV7) and Pneumococcal Polysaccharide Vaccine (PPSV)
Each year in the United States, 6,000 cases of pneumococcal meningitis are reported, which is the most serious type of bacterial meningitis, according to the National Institute of Neurological Disorders and Stroke. Caused by the bacterium Streptococcus pneumonia, pneumococcal meningitis causes death in 20 percent of patients and long-term neurological complications in 25 to 50 percent of patients, added MedlinePlus.
