Which pneumonia vaccine is best for COPD with diabetes?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am 62 and have diabetes plus mild COPD. I read about pneumonia vaccines for people like me, but I am confused about which one to take, PCV15 or PPSV23. Kindly answer my following questions:

  1. Do I need both or just one?

  2. How long does it last before I need another dose?

  3. Can I take it along with the flu shot or COVID booster?

I had pneumonia once years ago, and it was horrible, high fever, I could not breathe. I just want to avoid that again. Are there any serious side effects to these vaccines besides soreness or mild fever?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

You are absolutely right to think about pneumonia prevention, especially since you have diabetes and mild COPD (chronic obstructive pulmonary disease). Both conditions make your lungs more vulnerable to infections, and vaccination is one of the most effective ways to protect yourself.

There are two main pneumonia vaccines, PCV15 (Pneumococcal Conjugate Vaccine 15-valent) (Prevnar 15) and PPSV23 (Pneumococcal Polysaccharide Vaccine 23-valent) (Pneumovax 23). PCV15 (Prevnar 15) is a conjugate vaccine that covers 15 important strains, while PPSV23 (Pneumovax 23) covers 23 strains.

If you have never had any pneumonia vaccine before, the best approach is to take a single dose of PCV15 first, followed by PPSV23 after one year. If your doctor has access to PCV20 (Pneumococcal Conjugate Vaccine 20-valent) (Prevnar 20), that vaccine alone is enough; you will not need the PPSV23 later.

Protection usually lasts at least five to ten years, and sometimes a PPSV23 booster is advised after five years for those at very high risk or with chronic lung conditions.

You can safely take the pneumonia vaccine along with your flu shot or COVID (coronavirus disease) booster, just in different arms. There is no reduction in effectiveness or extra risk from combining them, and it helps build strong protection before winter or infection seasons.

Side effects are generally mild, some soreness or redness at the injection site, low-grade fever, or mild fatigue for a day or two. Serious reactions are extremely rare. Given your history of pneumonia, diabetes, and COPD, the protection these vaccines offer far outweighs any minor discomfort.

I hope that this answers your query.

Kindly follow up if you have more doubts.

Thank you.
