IMPACC Study Access
Migration Notice — May 20, 2026
IMPACC studies (SDY1760 and SDY2112) are being migrated to AccessClinicalData@NIAID (ACD) effective May 20, 2026. After this date, data access will be managed exclusively through ACD. See the IMPACC Study Access page for current guidance.

The document below provides a step by step guide for accessing the data when starting from the ImmPort study accession SDY1760.
End to End Workflow starting with Shared Data
Alternately the process for data access can be initiated directly from the IMPACC publication. A step by step guide for accessing the data when starting from the publication is noted below.
