Specialized doctors worldwide

Who conducts research into primary immunodeficiencies (severe)? Everyone here comes from a public registry: as principal investigator of a study at ClinicalTrials.gov, or as last author of publications in PubMed. Those are two different things, so we put them in two lists side by side instead of merging them into one figure.

Where these doctors work
Click or point to a dot to see who works there. 28 of the 75 physicians are on the map — we only place those who work at an institute whose city we know, and don't guess the rest.

This is not a referral and not a judgment on care. We know nothing about how these people treat, whether they accept patients, or how to reach them. We do not display contact details. If you want a second opinion or a referral, go through your own specialist.
