Detailed Description
This is a single arm, open-label clinical study. 34 participants aged 18 years and older who have completed the 2 doses of administration of inactive vaccines will be enrolled in this study to evaluate the safety and immunogenicity of V-01.
The participants will be collected blood before immunization, on day 7, day 14, day 28, day 90 and 6 month to evaluate humoral immunity.
All adverse events (AEs) within 30 minutes and 0-7 days after booster immunization, and unsolicited AEs from 8 to 28 days after booster immunization, as well as SAEs and AESIs from the first vaccination to 12 months after booster immunization will be collected from all participants.
