What is the relationship between asplenia and encapsulated bacteria?
People with asplenia (frank or functionally via disease) are more susceptible to infection by encapsulated bacteria.
Therefore, asplenic patients are vaccinated against Neisseria meningitis, Haemophilus influenzae, and Streptococcus pneumoniae.
These vaccines can be remembered with the mnemonic: NHS.
These three are also important because they produce IgA protease, cause meningitis, and take up DNA from the environment for transformation.
