IMPACC Study Access (SDY1760 & SDY2112)
The Immunophenotyping Assessment in a COVID-19 Cohort (IMPACC) studies (SDY1760 and SDY2112) are being migrated from ImmPort to AccessClinicalData@NIAID (ACD) effective May 20, 2026. After this date, ImmPort will no longer support download of these studies.
For information on how to request access — including creating an ACD account, submitting a DAR, and accepted IAL2 login options — see the Controlled Data Access page.
Restricted use
IMPACC data are limited to use for COVID-19/SARS-CoV-2 basic and clinical research only.
Studies
| ImmPort Accession | Description | ACD Study | Access |
|---|---|---|---|
| SDY1760 | IMPACC — Immunophenotyping Assessment in a COVID-19 Cohort (primary cohort) | SDY1760 | Request Access via ACD |
| SDY2112 | IMPACC — Extended Cohort | SDY1760 (same DAR) | Covered by SDY1760 DAR |
Note
A single DAR for SDY1760 on ACD covers access to both SDY1760 and SDY2112. Both ImmPort studies are treated as a single entity in the ACD system.
Existing ImmPort Access
Note
Active, unexpired ImmPort-based access for IMPACC studies will be honored in ACD — you do not need to submit a new DAR if your current approval has not expired. After creating your ACD account, contact ImmPort or ACD support to have your existing access transferred.
If your prior ImmPort-based access has expired, you must submit a new DAR through ACD.
