MenACYW: MenQuadfi™, Menveo™ and Nimenrix®
Meningococcal disease is caused by the bacteria Neisseria meningitidis. It is very rare, however once infected, the disease can progress quickly and have serious consequences.
Normally, some people carry this bacteria in their throat or nose without getting sick. In rare cases, this bacteria can cause serious disease and may spread to others. It can lead to meningitis (a brain infection), septicemia (a blood infection), as well as complications like hearing loss, brain damage, loss of limbs and even death.
Meningococcal disease can affect people of any age. However, it is most common in children under five years old, teens and young adults who are not vaccinated against the disease.
There are many strains of meningococcal infection that can cause illness. Strains A, B, C, Y, W have a vaccine to prevent infection. See a health care provider right away if you have any symptoms of meningococcal disease.
The MenACYW vaccines protect against four strains of the bacteria: A, C, Y, and W. The vaccines build an immune response in the body to provide protective antibodies to fight infections. The vaccine is 80 to 85% effective.
The effectiveness of the vaccine decreases over time, and so people who are identified as close contacts of someone with the disease may be recommended to get another dose.
Conjugate meningococcal vaccines and the meningococcal B vaccines should be administered to pregnant individuals, especially for those individuals at high risk for invasive meningococcal disease (IMD), travel to a high-risk area; post-exposure prophylaxis; or during an outbreak. Although these vaccines have not been studied extensively in pregnant individuals, there are no theoretical reasons to expect harm to the pregnant individual or infant. Meningococcal vaccines may be given to individuals who are breast feeding.

Adults born in 1997 or later, who have never received a Meningococcal vaccine is eligible and recommended to get vaccinated. Generally, if you were vaccinated with MenACYW in or after grade 7, you are up-to-date.
