Answer 18

Give the patient either PCV20 or PCV21 at or greater than five years after their last pneumococcal vaccination. If the patient is older than 65 years, engage in shared decision-making to determine whether to administer PCV20 or PCV21, ensuring it is given at least 5 years after their most recent pneumococcal vaccination.

Risk factors for invasive pneumococcal disease:

chronic heart disease, chronic lung disease, chronic renal disease (CKD or nephrotic syndrome), chronic liver disease (including secondary to excessive alcohol use), diabetes mellitus, CSF leak, cochlear implant, functional or anatomical asplenia (including sickle cell disease), immunosuppression from disease (including HIV) or treatment, and smoking.

Administer PCV15 or PCV20 first, then PPSV23 at least 8 weeks later.

When PCV20 is given, they do not require PPSV23.

Question 23

Is the PCV13 vaccine given anymore?

Answer 23

No, as of April 2024 this is no longer available.

If a patient has only obtained one dose of PCV13, then they need one dose of PCV20 or PCV21 (the same applies to PCV7). A patient does not need to wait one year after receiving PCV13 to receive a dose of PCV20 or PCV21.

Question 24

In what instances are the pneumococcal vaccines given to patients earlier than 65 years old?

Answer 24

The pediatric series (2 months, 4 months, 6 months, Booster at 1 year).

Vaccinate patients (older than 19 and less than 65 years old) who are at risk for pneumococcal infections. These are patients who have CSF leaks, cochlear implants, smoke, have liver disease or alcoholism, have COPD or other lung diseases like asthma or CF, are asplenic, have chronic heart disease or chronic kidney disease, are diabetic, or are immunocompromised due to immunotherapy, organ transplant, cancer (i.e. leukemia), or have contracted HIV.

If the patient is given PCV15, then the patient must also be given PPSV23, which is given 1 year after PCV15 but can be given as early as 8 weeks for immunocompromised patients. If the patient is given PCV20, then they do not require an additional vaccination for pneumococcous.

Question 25

What Pneumococcal vaccine is given to patients over 65 years old?

Answer 25

Give either PCV15 or PCV20 for all patients over 65 years old.

If the patient is given PCV15, then the patient must also be given PPSV23, which is usually given 1 year later.

An exception to the 1-year rule is allowed for the adult patients with immunocompromising conditions, cochlear implants, or CSF leaks, where in these cases, the follow-up vaccine can be given ≥ 8 weeks after a previous pneumococcal conjugate vaccine. If PPSV23 is unavailable, administer another dose of PCV20 or PCV21.

If the patient is first given PCV20, then they do not require a follow-up vaccination for pneumococcus.

Question 26

What is the minimum age for PCV15 and PCV20?

Answer 26

6 weeks.
