   1. Chronic illness (including Corticosteroid dependent Asthma)
   2. Functional Asplenia or anatomic Asplenia
   3. Immunocompromised state
   4. Renal disease (e.g. Nephrotic Syndrome, Renal Failure)
5. Dosing
   1. Dosing regimens are being modified in 2022 by CDC
      1. Prevnar 20 is sufficient alone, and does not require Pneumovax
      2. GIve Prevnar 20 alone (or Vaxneuvance AND Pneumovax 23)
   2. See Prevnar for dosing Pneumococcal Vaccine schedules
   3. Pneumovax 23 Indications (when Vaxneuvance or Prevnar 13 are used)
      1. One dose of Pneumovax 23 is sufficient for most patients at age 65 years
      2. Indication for single dose ages 2 to 64 years
         1. See Indications above
         2. Give a second dose at age 65 or at least 5 years after the last dose
      3. Indication for 2 doses at more than 5 years apart at ages 2 to 64 years
         1. Give third dose at age 65 years or at least 5 years after the last dose
         2. Chronic renal disease (Renal Failure, Nephrotic Syndrome)
         3. Asplenia
         4. Sickle Cell Anemia
         5. Immunocompromised state
            1. HIV Infection
            2. Leukemia
            3. Lymphoma
            4. Multiple Myeloma
            5. Iatrogenic (e.g. organ transplant, Radiation Therapy, Chemotherapy)
6. Precautions
   1. Administer to high risk women before pregnancy
   2. ACIP recommends avoiding in pregnancy
   3. Pneumococcal Vaccine may be given on same day as other Vaccines (e.g. Influenza Vaccine, Shingles Vaccine)
      1. PrevnarVaccine may have reduced Antibody response when given with Influenza Vaccine
      2. However, given both Vaccines (Prevnar and Influenza) does not reduce their efficacy
