Secondary Immune Deficiency and Its Impact on Long-Term Health w/ Dr. Fulvio Salvo

immune health podcast Aug 27, 2026

What if the reason you keep getting sick is not simply bad luck, seasonal viruses, or a string of unrelated health problems, but an immune system that has quietly become less effective over time?

Most of us think of immune deficiency as a rare genetic condition discovered in childhood. But a far more common form can develop later in life. 

Because the symptoms often appear separately, patients may spend years moving between specialists without anyone asking the question that connects the entire picture: Is the immune system functioning the way it should?

In this episode, we explore secondary immune deficiency and why it remains so easy to miss. Joining me is Dr. Fulvio Salvo, an internationally experienced allergist and clinical immunologist who has practiced at leading institutions in Italy, the United Arab Emirates, and Australia. 

He helps us understand how genetics, environment, nutrition, lifestyle, and modern medicine can intersect to strengthen (or gradually undermine) our immune defenses.

 

Secondary immune deficiency is not a defect in the blueprint. It is a defect in the maintenance, something that occurs later in life and damages your defensive wall against the world around you. -Dr. Fulvio Salvo
