Study Title:

Evaluation of the Safety and Immunogenicity of a Third Dose of PV-001 in Healthy Women Aged 19-45

Objective:

To assess the safety and antibody response of a third dose of PV-001 in healthy adult female participants.

Key Questions Is PV-001 safe? What adverse events may occur after vaccination? Does PV-001 produce an effective immune response?

Participant Activities :
