The Journal of Immunology (The JI) is pleased to announce that its 2025 Impact Factor has increased to 4.0, an 18% rise from 2024. This growth demonstrates expanding visibility and influence and reflects the journal’s global reputation, with authors from 92 countries and 2,479 institutions represented in the 2025 impact factor.
While the Impact Factor reflects recent citation activity, the journal’s cited half-life of 15.7 years shows that research published in the journal remains relevant and continues to be cited long after publication. These metrics together highlight both the journal’s immediate impact and the enduring importance of its published research, emphasizing The JI’s role in advancing foundational discoveries that shape the field over time.
As a society journal, The JI is committed to publishing rigorous, high-quality research across all areas of immunology while upholding rigorous peer-review standards and an unwavering commitment to scientific integrity.
