Donate Now

There are three meaningful ways to support the Jeffrey Modell Foundation and help those living with Primary Immunodeficiency: Make a donation to fund research, advocacy, and education. Donate plasma to support lifesaving treatments. Or shop our online store—where every purchase helps advance our global mission.

Make a Gift

Support research, advocacy, and global awareness for Primary Immunodeficiency. Your donation directly helps drive progress toward early diagnosis, better treatment, and lasting impact.

Donate Now

Give Plasma, Save Lives

It takes 130 plasma donations to treat one PI patient for a year. Plasma can't be manufactured—it must come from donors. Help meet the growing need and give the gift of life.
