MENVEO is a vaccine used to protect against meningococcal disease, which is caused by the bacteria Neisseria meningitidis. This disease can lead to serious infections like meningitis (inflammation of the protective membranes covering the brain and spinal cord) and septicemia (bloodstream infection). MENVEO targets four of the major groups of this bacteria - A, C, W, and Y - helping to stimulate the body's immune system to provide protection against these strains. It is administered via injection and is recommended for individuals starting from 2 months of age and older, including adolescents and adults who are at increased risk of meningococcal disease. The vaccine is especially important for people traveling to countries where the disease is common, those in close living situations like college dormitories, or individuals with certain medical conditions that increase their risk of infection.
