Menactra (meningococcal conjugate vaccine) is used to prevent infection caused by meningococcal bacteria.

Menactra works by exposing you to a small dose of the bacteria or a protein from the bacteria, which causes your body to develop immunity to the disease. Meningococcal conjugate vaccine contains four of the most common types of meningococcal bacteria (serogroups A, C, W, and Y).

Purchase Remark: Must prescribe and inject by doctors.
