response might be diminished
what is the advise for asplenic travelers?
if develop fever, initiate broad-spectrum AB self-treatment;
avoid travel to where lacking immediate access to high-standard medical care;
Many clinicians advise a 3-month delay after immune reconstitution of HIV treatments (usually 6 months after initiation of antiretroviral therapy) if possible, before immunizations are administered because?
in order to maximize the immune response to vaccination.
