How and when should you receive the meningococcal vaccine?

You receive the MCV4 as a single dose, injected into a muscle. You receive the MPSV4 as a single dose injected under the skin.

In most cases, adults only need one dose. But if you remain at risk, you may need a booster.

Are there any dangers or side effects associated with the meningococcal vaccine?

Neither vaccine can cause meningococcal disease.

If you have a reaction to the meningococcal shot, it will most likely be mild. Side effects may include:

• Mild pain and redness at the injection site
• Slight fever

In rare cases, a meningococcal vaccine may cause a severe allergic reaction. Signs of this include:

• Hoarseness, wheezing, trouble breathing, or swallowing
• Hives, itching, skin warmth, or redness
• Paleness
• Stomachcramps, diarrhea, or vomiting
• Anxiety or headache
• Weakness, dizziness, lightheadedness, or loss of consciousness

People have reported developing Guillain-Barré syndrome after having the MCV4. This may lead to symptoms such as a tingling or numbing sensation, and muscle weakness.

If you have any signs of a severe reaction:

• Call 911 or go to the emergency room immediately.
• Describe when you had the vaccine and what happened.
• Have a health care professional report the reaction.
