meningococcal ABCWY pentavalent vaccine

Meningococcal ABCWY pentavalent vaccine protects against meningococcal disease caused by the bacteria Neisseria meningitidis serogroups A, B, C, W, and Y. Meningococcal disease is a severe and potentially life-threatening bacterial infection of the brain, spinal canal, and bloodstream. There are 13 strains of N. Meningitidis, but serogroups A, B, C, W, X, and Y are most common in the United States.

Meningococcal disease can affect anyone, including healthy individuals, and can become fatal within 24 hours. It’s more common in children under 1 year old, young adolescents and adults aged 16-23, and adults over 65. The vaccine is given as two intramuscular injections 6 months apart to individuals aged 10 to 25.

N. meningitidis lives in the nose and throat of about 10% of the population without causing disease. It spreads through saliva and nasal droplets and can cause invasive disease in vulnerable individuals. The bacteria enter the bloodstream, cross the blood-brain barrier, and infect the membranes of the brain and spinal cord.

Meningococcal ABCWY pentavalent vaccine contains protein and carbohydrate fragments from A, B, C, W, and Y strains of N. meningitidis. It stimulates the immune system to produce antibodies that recognize the bacteria and kill them, protecting against severe disease in the future.

The vaccine is conjugated with a tetanus bacterial toxoid to enhance the immune response. It does not contain preservatives.
