U.S., March 19 -- ClinicalTrials.gov registry received information related to the study (NCT07479537) titled 'Acquired Tick Resistance in Naturally Exposed Participants' on Dec. 03, 2025.

Brief Summary: Tick-borne diseases are increasing worldwide, and there are currently few effective ways to prevent them. One promising new strategy is to develop a vaccine that targets the tick itself ("anti-tick vaccine") to block the transmission of multiple pathogens.
