Different illnesses can cause meningitis and several vaccines that protect against them. There are 2 kinds of meningococcal vaccines (MCV4 and MenB). These vaccines are about 85-90% effective in preventing meningococcal disease. These vaccines together protect against the five most common strains of meningococcal bacteria found in the U.S.

Both the Meningococcal conjugate vaccine and the Meningococcal B vaccine are very safe, and serious side effects are extremely rare. About half of the people who get the vaccine will have pain/redness where the vaccine was given or a mild fever.

Different infections can cause complications, including meningitis. It is important to protect your family from all the diseases that can cause meningitis. Talk to your healthcare provider about which vaccines your family members need:

  • Meningococcal conjugate vaccine: First dose at 11 – 12 year old of age with a booster dose at 16 years old. Teens and young adults (16 – 23 years of age) also may get a serogroup B meningococcal vaccine.
  • Meningococcal B vaccine: The MenB vaccine should be given to teenagers between 16 – 18 years of age.
