Hello, Getting the meningococcal meningitis vaccine twice is generally considered safe and is unlikely to cause harm. In fact, some people may need to receive a booster dose of the vaccine, depending on their age, health status, and other factors. However, it s important to talk to your healthcare provider about your specific situation and follow their recommendations for vaccination. They can provide guidance on when to receive the vaccine and how often, based on your age, health history, and other factors. In some cases, receiving the meningococcal meningitis vaccine too frequently may not provide additional protection, and could increase the risk of side effects. That s why it s important to follow the recommended vaccine schedule and discuss any concerns with your healthcare provider. Take care. Hope I have answered your question.
