Clinical Study on Immunogenicity and Safety of Lyophilized Vero Cell-Derived Human Rabies Vaccine in Special Populations
China180 participantsStarted 2025-08-15
Plain-language summary
This study adopts a parallel-controlled design and includes a study group and a control group. The study group will enroll 150 special population participants (including non-HIV-related immunocompromised individuals, patients with chronic diseases, and elderly individuals) who receive their first post-exposure treatment following WHO category II or III rabies exposure. The control group will include 30 healthy adults with similar exposure.
Blood samples will be collected at Day 14 and Day 90 after completion of the full vaccination schedule to assess rabies virus neutralizing antibody seroconversion rates and titers. Immunogenicity and antibody persistence will be compared between the two groups. Additionally, all adverse events occurring within 30 minutes and within 7 days after each dose will be recorded to evaluate safety.

Inclusion criteria
. Long-term immunocompromised status due to conditions including, but not limited to: clinically confirmed primary immunodeficiency diseases; hematologic or solid organ malignancies; aplastic anemia; clinically confirmed autoimmune diseases with immunosuppressive therapy lasting 4 weeks or longer within the past 12 months prior to enrollment; history of splenectomy or other major immunologic organ removal; hematopoietic stem cell or solid organ transplantation within 2 years prior to enrollment.
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Rabies virus neutralizing antibody (RVNA) seropositivity rate and antibody level at Day 14 after full vaccination
Timeframe: 14 days post completion of full vaccination.
2
Rabies virus neutralizing antibody (RVNA) seropositivity rate and antibody level at Day 90 after full vaccination
Timeframe: 90 days post completion of full vaccination.
