Are you trying to decide whether to submit a NIH R01 vs. a R21 application? This information from NIH may help. Visit NIH Nexus R01 and R21
NIH summarizes the information as shown below:
- The R21 mechanism is increasingly popular – we are seeing many more applications and awards, with growth rates exceeding those of R01 grants – but also highly competitive.
- Most R21 applicants and awardees have previously received some NIH funding; only 34% of R21 awardees were new NIH investigators.
- Over 15% of R21 awards are followed by at least one similar R01 application, but fewer than 5% of R21 awards are followed by at least one similar funded R01 project.
