About this Summary & Analysis

Checking access…

The National Institutes of Health's (NIH) policy change, effective July 1, 2025, which eliminated the 12-month embargo on publicly funded research, significantly accelerated the public availability of NIH-supported articles in PubMed Central. Compared to non-federally funded articles, NIH-supported research saw a 5.6 percentage point increase in availability within one week of publication. This effect was most pronounced in journals not listed in the Directory of Open Access Journals, where immediate access doubled from 11% to 22%. Despite this acceleration, the analysis indicates that substantial delays in public access still exist.

Why it matters

This development indicates that policy changes can significantly influence the speed and breadth of public access to research outcomes, thereby enhancing transparency and knowledge dissemination. Organizations and research institutions relying on public funding or engaging in publicly accessible research must understand the impact of such mandates on their publication strategies and compliance requirements. It also highlights the ongoing challenge of achieving fully immediate and open access across all publishing venues.

Key insights

  • The NIH policy change in July 2025 eliminated the 12-month embargo on public access to funded research, mandating immediate availability in PubMed Central.
  • Public availability of NIH-supported articles in PubMed Central within one week of publication increased by 5.6 percentage points more than non-federally funded articles.
  • The accelerated access was primarily observed in journals outside the Directory of Open Access Journals (DOAJ), where immediate access for NIH-supported articles doubled from 11% to 22%.
  • No significant differential change in immediate public access was noted for NIH-supported articles published in DOAJ-listed journals.
  • Despite the policy's positive impact, significant delays in achieving widespread immediate public access to NIH-funded research persist.
