When records and memory differ, it’s best to revaccinate

Dear Dr. Roach: Iama 77-year-old female. I am current on all vaccines, but I do have a question about the pneumococcal vaccine.

My physician recommends I get one. I thought I had gotten that a few years ago from my physician who retired. We are unable to find in my medical file that it was given. That was a time when they were switching to all computer access charting. I got no confirmation from the pharmacy sometimes gives my vaccines.

My physician recommends I get another one since we have no record or proof of it being administered. Is it safe to get it again? I completed my Moderna series, so I would get the pneumococcal vaccine in three months. — V.W.

Dear V.W.: There are two kinds of pneumococcal vaccines. These protect against pneumonia and other diseases. They are sometimes referred to as pneumonia vaccines, but pneumococcal vaccine is more correct.

I am sure your doctor is recommending the pneumococcal polysaccharide vaccine. This one is called PPSV-23, or by its brand name, Pneumovax. The other, the pneumococcal conjugate vaccine, protects against 13 types.

The Advisory Committee on Immunization Practices downgraded its recommendation about the PCV-13 from recommending to all 65-yearolds to having a discussion about whether it’s appropriate on an individual basis.

The choice is whether to give the PPSV-23 again — or not. The balance of risks is in favor of giving the vaccine. Getting it twice is not harmful. It’s a well-tolerated vaccine, with far fewer side effects than the Moderna vaccine you just took. I’ve had patients get it twice with no ill effects.
