What is meningococcal conjugate vaccine?

Meningococcal disease is a bacterial infection that can infect the spinal cord and brain and cause meningitis, which can be fatal or lead to permanent and disabling medical problems.

Meningococcal disease spreads from person to person through small droplets of saliva expelled into the air when an infected person coughs or sneezes. The bacteria is usually passed through close contact with an infected person, especially through kissing or sharing a drinking glass or eating utensil.

Meningococcal conjugate vaccine is used to prevent infection caused by serogroups A, C, W, and Y. This vaccine helps your body develop immunity to meningitis, but will not treat an active infection you already have.

The Menactra brand of this vaccine is for use in children and adults between the ages of 9 months and 55 years old. Menveo is for children and adults between the ages of 2 months and 55 years old. MenQuadfi is for adults and children at least 2 years old.

Like any vaccine, meningococcal conjugate vaccine may not provide protection from disease in every person.

Keep track of all side effects you have. If you need a booster dose, you will need to tell the vaccination provider if the previous shot caused any side effects.
