Linking serology and rabies case data: implications for raccoon rabies management

Effective wildlife disease management depends on reliable metrics to guide programmatic decisions. Rabies virus (RV) circulates in wild carnivore populations in the United States (U.S.). One primary management goal is to prevent the spread of and eliminate the raccoon (Procyon lotor) RV variant (RRV) using landscape level oral rabies vaccination (ORV). Management impacts are measured using two approaches: determining the raccoon population proportion with serum RV neutralizing antibodies (RVNA) post-ORV (i.e., raccoon RVNA seroprevalence) and evaluating RRV case trends.

Threefold Saline Dilution of KEDRAB®, a Standard Human Rabies Immune Globulin (150 IU/mL), Preserves Potency and IgG Integrity While Expanding Volume for Challenging Wound Infiltration

Background: KEDRAB® (Human Rabies Immune Globulin) is indicated for passive, transient post-exposure prophylaxis of rabies infection in persons of all ages following contact with a rabid or possibly rabid animal, administered concurrently with a full course of rabies vaccine.

RABIES VIRUS EXPOSURE IN WILD BOARS IN A PERI-URBAN AREA BY SEROLOGICAL ANALYSIS

Introduction: Wild boars (Sus scrofa) are an invasive species widely distributed across various biomes, exhibiting generalist behavior and frequently interacting with domestic animals, wildlife, and humans. Although they are not reservoirs of the rabies virus, they can serve as sentinels of viral circulation, reflecting exposure to ecosystems shared with bats and other mammals. Serological surveys are important for assessing rabies virus circulation, supporting epidemiological surveillance and contributing to prevention and control strategies.

ONRAB® revisited: Contemporary Characterisation of an Established Recombinant Adenoviral Vector Rabies Vaccine

Oral rabies vaccination (ORV) is an effective approach for controlling and eliminating terrestrial rabies in mammals and has been successfully implemented in North America and Western Europe. Most oral rabies vaccines are based on modified, live-attenuated rabies viruses. Although modern second- and third-generation vaccines are highly effective and have excellent safety profiles, some wildlife species, including raccoons and skunks, respond only to very high concentrations of certain vaccine constructs, which are not feasible under routine production conditions.

Refinement of a bioluminescent mouse model for preclinical evaluation of rabies therapeutics

Background: Effective therapeutics for clinical rabies require animal models in which treatment can begin after virus reaches the brain, but before progression to a humane endpoint. Rapid, asynchronous disease onset in conventional mouse models makes this interval difficult to identify. We refined a bioluminescent model for preclinical therapeutic evaluation of rabies using a recombinant rabies virus expressing NanoLuc luciferase (RABV-N2c-NL).

Exploiting Thermotolerance to Optimisie Rabies Control Through Community-based Dog Vaccination Delivery and the Value of an Integrated Approach to Rabies Elimination

Background: Rabies elimination requires sustained mass dog vaccination (MDV) alongside timely access to post-exposure prophylaxis (PEP). We present linked studies examining whether alternative MDV delivery and integrated One Health strategies can improve coverage, affordability and impact.

The immune response and the geographical origin of dogs: a never-ending story

For the use of an already licensed vaccine in a new country, the need for local clinical efficacy studies varies among countries. Many countries accept assessments from trusted regulatory authorities, and additional local studies are not required. Other countries may require a local bridging immunogenicity study. However, is the latter justified when sufficient clinical data from different countries are already available?

Multiple disease threats at the border facilitated by an invading species with ties to an invasive species

Feral swine are well established along the border with Mexico especially within Texas with approximately four million animals.  They have the potential of being a prey species for the common vampire bat (Desmodus rotundus). Vampire bats are expanding their range northwards along both the east and west coasts of Mexico with the potential to become part of the fauna of the United States of America. In Mexico, all but areas have programs to address rabies from vampire bats. Suitable habitat in the southern US has been identified as capable of hosting vampire bats.
