Pediatrics/low iga and pneumococcal vaccine
My 9 year old has tested for low IgA and his IgG is on the pretty close to the lowest end of the normal range. Is this something I should keep monitoring? He is pretty healthy though had one acute infection that required hospitalization and IV antibiotics. and I think he has sinus issues though I do not know how thats diagnosed. Basically he has an on off postnasal drip. His response to the pneumococcal vaccine was only 30%. I dont think re vaccination is recommended. What steps should I take going forward? Thanks
I am not an expert in this precise field, but I know that many kids with IgA deficiency fail to mount a supposedly adequate response to the pneumoccocal vaccine. The vaccine won't hurt them, it just may not be fully effective.
I don't think additional vaccines would enhance this response. I assume that you have a pediatric infectious disease person available, at least through your doctor, and if this person says otherwise, I would be happy to defer.
Good luck, Dr. Olson
