The meningococcal meningitis vaccine (conjugated or nonconjugated) can cause mild side effects, including redness or pain at the injection site, headaches or fatigue. Some people who get the shot develop a fever. You may also experience a vague uncomfortable feeling after getting the vaccine. However, these side effects are far less serious than meningococcal disease. Severe allergic reactions may occur within minutes or hours of having the vaccination. These are signs of an allergic reaction:

  • Trouble breathing
  • Hoarseness or wheezing
  • Hives
  • Paleness
  • Weakness
  • Fast heartbeat or dizziness

If these signs appear, call 911.
