Gilead Sciences is a corporate/pharmaceutical funder whose philanthropic activity centers on advancing diagnosis, treatment, prevention and equitable access for viral diseases (especially HIV and viral hepatitis), emerging infectious diseases, and related community health needs. They support a mix of clinical research, public health programs, community-based organizations serving marginalized populations (including LGBTQ+ people and people who use drugs), and capacity-building efforts that improve care delivery and linkage to treatment. Gilead gives both domestically and globally and often coordinates grants with programmatic partnerships, product donations, and targeted initiatives in crisis response and health equity.
Combination of programmatic initiative grants and partnerships (including RFP-driven and invitation-only programs), philanthropic foundation grants, in-kind product donations, and awards/support for clinical research; funding ranges from small community grants to multi-year, larger institutional awards and is focused around defined programs and campaigns rather than open unrestricted funding.
