Up to 2,600 people develop meningococcal disease each year in the United States, according to the Centers for Disease Control and Prevention. As of 2010, two meningitis shots can help prevent the development of this life-threatening bacterial infection: MCV4 and MPSV4. Prior to immunization, people should discuss the potential dangers of these meningitis shots with a medical professional.
Side Effects
Side effects are a potential danger associated with both meningitis shots. These side effects are generally mild and include injection site pain and redness or a low-grade fever, the National Meningitis Association reports. Fever or reactions at the injection site can arise immediately after vaccination and typically subside within two days of onset. People who experience an unusually high fever or persistent injection site discomfort should contact a doctor for further evaluation and care.
Guillain-Barré Syndrome
People who receive the MCV4 meningitis shot may be in danger of developing Guillain-Barré Syndrome, a severe disorder of the central nervous system, according to the CDC. A personal or family history of Guillain-Barré Syndrome may increase a person's risk of developing this side effect following immunization. People who experience symptoms of Guillain-Barré Syndrome, such as numbness, tingling, difficulty walking, lower back pain, heart rate irregularities or breathing problems after receiving the MCV4 vaccine should seek immediate medical care.
Hypersensitivity Reaction
Though infrequent, hypersensitivity reactions to the MCV4 and MPSV4 meningitis shots can occur in people prone to allergies. Symptoms of a hypersensitivity reaction include wheezing, vocal hoarseness, rapid heart rate, dizziness, hives, weakness and pale skin, notes the CDC. Allergic people typically develop hypersensitivity reaction symptoms within a few minutes following receipt of a meningitis vaccine. If any of these symptoms emerge, affected people require immediate medical attention to prevent life-threatening complications.
