What is Menveo (Men-ACYW)?

Meningococcal disease is a bacterial infection that can affect the spinal cord and brain, leading to meningitis. This condition can be fatal or result in permanent and disabling health issues.

Meningococcal disease can be transmitted from one person to another through tiny droplets of saliva that are released into the air when an infected person coughs or sneezes. The bacteria are typically spread through close contact with an infected person, especially by kissing or sharing a drinking glass or eating utensil.

Menveo (Men-ACYW) is used to prevent infection from serogroups A, C, W, and Y. This vaccine helps your body build immunity to meningitis, but it will not treat an existing infection.

The Menactra brand of this vaccine is for children and adults aged 9 months to 55 years old. Menveo is for children and adults aged 2 months to 55 years old. MenQuadfi is for adults and children 6 weeks of age and older.

Like any vaccine, Menveo (Men-ACYW) may not protect every person from disease.
