What is meningococcal meningitis?

It’s a life-threatening infection caused by bacteria.

It’s a form of meningococcal disease, often called meningitis, caused by bacteria that can live in the nose and throat. Meningitis is uncommon but can progress from flu-like symptoms to life-threatening in as little as 24 hours.

The 5 leading types of meningococcal bacteria—A, B, C, W, and Y—cause nearly all cases.

Signs and symptoms

Symptoms can feel like the flu at first.

Symptoms can come on quickly and may get worse over time. Early symptoms may feel like the flu and can include:

• Fever and chills
• Nausea and vomiting
• Generalized muscle aches
• Stiff neck or headache
• Sensitivity to light
• Confusion

Additional long-term consequences can include loss of limbs, hearing loss, and brain damage (including learning disabilities). It’s important to pay attention and seek care if something feels off.

How it spreads

It can spread through close contact.

Meningococcal bacteria can spread through close or prolonged contact with someone else’s saliva, like:

  • Coughing
  • Kissing
  • Sharing food, drinks, or utensils
  • Sharing items that touch the mouth, like lipstick or lip balm
  • Crowded social gatherings
  • Living in dorms or shared housing

Here’s what to know about meningococcal meningitis vaccines.

card

What are they?

Meningitis vaccines help protect against different types of meningococcal bacteria.

Some protect against 4 types (A, C, W, and Y), while others protect against one type (B). There are also options that help protect against all 5 types.

You don’t need to have it all figured out. A quick assessment can help you understand whether your teen may still need protection against all 5 leading types and help you prepare for a conversation with their doctor.

card

Who are they for?

Pre-teens, teens, and young adults.

Most kids get their first meningitis vaccine at age 11 or 12. Starting at age 16, additional doses may be recommended to help make sure they’re vaccinated against all 5 leading types. Talk to their doctor to make sure they’re fully vaccinated.

Possible side effects?

Soreness

Fever

Headache

Meningococcal vaccines can cause mild side effects. These may include soreness or redness where the shot was given, tiredness, headache, or muscle pain. These side effects usually go away on their own within a few days.

Still have questions?

How can I check which meningococcal vaccines my teen has already received?

You can check your teen’s vaccination records through their doctor’s office, patient portal, or your state’s immunization registry (where available).
A doctor can help review what they’ve received and whether they may still need additional protection.

Even if they were vaccinated around age 11 or 12, they may need additional doses starting at age 16.

You can also use the risk assessment tool to help guide a conversation with their doctor about their protection.

How do I know which meningoccal vaccines my teen may need?

You don’t need to have it all figured out. Your teen’s doctor may mention different meningococcal vaccines.

Your teen’s doctor may mention different meningococcal vaccines and terms like these:

  • Monovalent: Protects against 1 of the 5 leading types (B)
  • Quadrivalent: Protects against 4 of the 5 leading types (A, C, W, and Y)
  • Pentavalent: Protects against all 5 leading types (A, B, C, W, and Y)

A quick assessment can help you understand whether your teen may still need protection against all 5 leading types and help you prepare for next steps with their doctor.

What should I know about meningococcal vaccine safety and side effects?

Meningococcal vaccines are approved for use and are monitored for safety. They can cause mild side effects such as soreness at the injection site, headache, fatigue, or muscle pain. Your teen’s doctor can help you understand what to expect and answer any questions.
