Intervention / Treatment
Detailed Description
NSV0001 is a quadrivalent influenza vaccine with the new adjuvant (ND002) administered by sublingual route.
This study will enroll healthy male adults. Participants will receive two doses of the vaccine, 4 weeks apart, and will stay in the investigational site for 2 consecutive days after each vaccination.
Participants will keep a patient diary to record the local and systemic reactions for one week after each vaccination. In addition, the safety monitoring will be extended through 6 months from the last vaccination to detect the potential immune mediated disorders (pIMD).
