Description
The National Institute of Allergy and Infectious Diseases (NIAID) announces a program that provides NIAID-supported K01, K08, and K23 recipients with the opportunity to apply for Exploratory and Developmental Research Grant (R21) support at some point during the final two years of their K award. Through the use of this mechanism, NIAID seeks to enhance the capability of its K01, K08, and K23 award recipients to conduct research as they complete their transition to fully independent investigator status (e.g., R01 support). The R21 grant mechanism supports different types of projects, including pilot and feasibility studies; secondary analysis of existing data; small, self-contained research projects; development of research methodology; and development of new research technology. The R21 is, therefore, intended to support research projects that may provide preliminary data to support a subsequent R01, or equivalent, application.
