There are 4 vaccines against Meningitis, the vaccine against Meningitis B, C, the pneumococcal vaccine and the conjugate vaccine against Haemophilus influenzae type b. They all protect against a different kind of disease.
Meningitis is a disease caused by a gram-negative bacterium called Neisseria meningitidis, which has different serogroups. This disease causes symptoms such as fever, headache, nausea, vomiting or signs of inflammation of the meninges, and when not diagnosed early can lead to death or leave sequelae such as deafness or brain damage.
Main vaccines
To combat the different types of Meningitis, the following vaccines are indicated:
1. Meningitis C Vaccine
This vaccine, also known as the C meningitis vaccine, is indicated to prevent meningitis caused by meningococcus serogroup C in adults or children. As the protection of this vaccine only has a duration ranging from 1 to 2 years, it is only indicated in cases or regions where there are outbreaks of the disease.
How to take:
The C meningitis vaccine should be administered with only 1 dose, which should be given intramuscularly and is part of the vaccination plan. The reinforcement should be applied in children up to 4 years old and in adolescents 12 and 13 years old.
2. Vaccine against Meningitis B
This vaccine can also be known commercially as bexsero and is indicated for protection against meningitis caused by meningococcus type B.
How to take:
- For children 2 to 5 months of age, 3 doses of the vaccine are recommended, at intervals of 2 months between doses. In addition, a booster should be done between 12 and 23 months of age;

For adults and children, only 1 dose is recommended to provide protection against the bacteria. After 5 years, the vaccine may need to be boosted, especially in people with a weakened immune system.
4. Conjugate against Haemophilus influenzae b
