Examples of such use is in organ transplant surgery as an anti-rejection measure and in patients with an overactive immune system, as in autoimmune diseases. Some people are born with intrinsic defects in their immune system, or primary immunodeficiency. [2] A person who has an immunodeficiency of any kind is said to be immunocompromised.
The official CDC guidance for moderately or severely immunocompromised patients 6 months and older who aren't vaccinated is to get two or three doses of the same brand of the updated COVID-19 vaccine.
The majority of CVID patients have normal B cell counts, suggesting the impaired antibody production is mainly a defect in the differentiation process of B cells into memory and plasma cells. There are also T cell abnormalities in CVID including counts, percentages, surface markers and function differences.

The tools immunocompromised patients now have at their disposal, while not as effective as when given to those with healthy immune systems, can still allow them to feel more comfortable, said Dr ...
An opportunistic infection is an infection caused by pathogens (bacteria, fungi, parasites or viruses) that take advantage of an opportunity not normally available.These opportunities can stem from a variety of sources, such as a weakened immune system (as can occur in acquired immunodeficiency syndrome or when being treated with immunosuppressive drugs, as in cancer treatment), [1] an altered ...
Examples of this in bacteriology are the overgrowth of endogenous Clostridioides difficile that occurs following treatment with a broad-spectrum antibiotic, and pneumonia or sepsis from Pseudomonas aeruginosa in some immunocompromised patients. [2] In virology, the definition is slightly different.
