What is it?
Meningococcal disease is caused by the bacterium Neisseria meningitidis.
Common symptoms of meningitis include fever, headache, and a stiff neck. Septicemia often causes symptoms such as fever, chills, muscle aches, and, in later stages, a dark purple rash.
There are two types of vaccination for meningococcal:
One type protects against serogroups A, C, W, and Y
The other type protects against serogroup B
What's the difference between them?
For meningococcal ACWY, one dose at 11-12 years old and a booster at age 16 is recommended
Meningococcal B is not a required vaccination. It is recommended if you have certain conditions or are high risk, but you can also choose to get vaccinated even if you are not in those categories. If you have questions or are interested in receiving this vaccine, please talk to your doctor.
For the menigococcal B vaccine, the doses depend on which vaccine you receive.
Bexsero is always a 2-dose series.
Trumenba is 2 doses if you are not high risk and 3 doses if you are high risk.
If you are high risk, the vaccine is recommended for people age 10 or older.
It is recommended for age 16-18 for people who are not high-risk.
Bexsero also provides some protection against gonorrhea because one of the active ingredients is outer membrane vesicles (OMVs), which contain surface antigens that are similar to proteins found on the surface of Neisseria gonorrhoeae, which causes gonorrhea.
