Percentages of Participants With Rabies-specific Serum Virus-neutralizing Antibody Titer (VNTs)
Rabies-specific serum response was defined as VNT ≥ 0.5 international units per milliliter (IU/mL). Rabies-specific serum VNT were measured using the WHO-recommended rapid fluorescent foci inhibition test (RFFIT). Serial dilutions of each serum sample are mixed with a standard dose of rabies virus before tissue culture cells are added. Virus infected cells are detected via a fluorochrome conjugated rabies-specific antibody. If the serum contains antibodies that bind and neutralize the virus, the infectivity of the virus is reduced. The virus neutralization end-point titer is defined as the highest sample dilution at which 50% of the observed microscopic fields contain ≥ 1 infected cell. The percentages of participants with rabies-specific serum VNTs ≥0.5 were taken as positive and were reported.
Time frame: Baseline (Day 1), Days 15, 43, 365, 547, and 730
Serum Geometric Mean Titers (GMTs) of Rabies-specific VNTs
Serum geometric mean titer (antilog mean of log-transformed VNTs) was obtained from measuring VNTs using the WHO-recommended rapid fluorescent foci inhibition test. The virus neutralization end-point titer (VNT) is defined as the highest sample dilution at which 50% of the observed microscopic fields contain \>=1 infected cell.
Time frame: Baseline (Day 1), Days 8, 15, 29, 36, 43, 57, 91, 182, 365, 547, and 730
The study was conducted at 2 investigative sites in Germany and Belgium between 12 October 2018 and 23 November 2021.

An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered an investigational product. An AE does not necessarily have a causal relationship with medicinal product. Vaccine-related MAAEs include any AEs for which the participant received medical attention, defined as hospitalization, an emergency room visit, or an otherwise unscheduled visit to or from medical personnel for any reason for which there is evidence to suggest a causal relationship between the study product and the adverse event. Number of participants with related MAAEs were reported.

An AE was defined as any untoward medical occurrence in a clinical study participant administered an investigational product. An AE does not necessarily have a causal relationship with medicinal product. AEs with a suspected potential immune-mediated disease etiology was considered as AESIs. AESI was assessed by the investigator. Vaccine-related AESIs was included as AESIs for which there was evidence to suggest a causal relationship between the study product and the adverse event. Number of participants with any related AESIs were reported.

Rabies-specific serum response was defined as VNT ≥ 0.5 international units per milliliter (IU/mL). Rabies-specific serum VNT were measured using the WHO-recommended rapid fluorescent foci inhibition test (RFFIT). Serial dilutions of each serum sample are mixed with a standard dose of rabies virus before tissue culture cells are added. Virus infected cells are detected via a fluorochrome conjugated rabies-specific antibody. If the serum contains antibodies that bind and neutralize the virus, the infectivity of the virus is reduced. The virus neutralization end-point titer is defined as the highest sample dilution at which 50% of the observed microscopic fields contain ≥ 1 infected cell. The percentages of participants with rabies-specific serum VNTs ≥0.5 were taken as positive and were reported.

Serum geometric mean titer (antilog mean of log-transformed VNTs) was obtained from measuring VNTs using the WHO-recommended rapid fluorescent foci inhibition test. The virus neutralization end-point titer (VNT) is defined as the highest sample dilution at which 50% of the observed microscopic fields contain \>=1 infected cell.
