How to Vaccinate Immunocompromised Patients

http://http://images.slideplayer.com/14/4441609/slides/slide_21.jpg

Before vaccinating an immunocompromised individual, the physician needs to take into account the varying severity of immunocompromised patients.

1) For severely immunocompromized patients not infected with HIV:

  • In general, severely immunocompromised patients should not be administered live attenuated vaccines. Doing so would promote microbial proliferation.
  • Vaccinations during chemotherapy and/or radiation therapy are advised against, due to a diminished antibody response.
  • Passive immunization or inactivated immunization is recommended for immunocompromised patients

2) For patients with HIV:

  • In general, HIV patients should not be administered live attenuated vaccines.
  • However, MMR vaccinations are recommended, regardless of HIV infection or lack thereof.
  • A specific type of polio vaccine (Enhanced Inactivated Polio Vaccine [eIPV]) is recommended for HIV-positive patients.
  • Pneumococcal vaccines (S. pneumoniae, meningitis, etc.) are recommended for HIV patients older than 2 years of age.
  • Before an HIV positive patient receive an Hib vaccine against H. influenzae, the physician should take into account the risk of disease and the calculated effectiveness in the patient.

3) For patients with conditions that can lead to a diminished immune function:

  • Certain antigens and certain vaccines will be more effective in a patient based on the medical condition that is compromising the patient’s immune response.
Renal failure Diabetes Hepatic Cirrhosis Asplenia
Serum antibody levels are lower Patients present with abnormal immune surveillance Patients often present with leukopenia (decreased leukocyte count), decreased complement activity, defects in leukocyte chemotaxis, and cell-mediated immunity defects Two weeks before a splenectomy, pneumococcal, meningococcal, and Hib vaccines should be administered
There is an increased risk of Hep. B and Pneumococcus infections One-time pneumococcal vaccine and an annual flu vaccines are recommended One-time pneumococcal vaccine and an annual flu vaccines are recommended Polyvalent pneumococcal vaccines (immunizes against multiple strains of a microbe) are recommended for patients older than 2 years of age
Immunizing the patient in the early stages of renal failure with repeat vaccinations or increased vaccine dosage is recommended Pneumococcal and flu vaccine does not have any contraindications with insulin or glucose treatment   Hib vaccines should be administered in infancy at the same dosage and frequency as healthy children
