Achieving scientific and regulatory success in implementing non-animal approaches to human and veterinary rabies vaccine testing: A NICEATM and IABS workshop report

Publication date: Available online 27 June 2019Source: BiologicalsAuthor(s): Rebecca Poston, Richard Hill, Cynthia Allen, Warren Casey, Donna Gatewood, Robin Levis, Laurent Mallet, Dean Smith, Geetha Srinivas, Catrina Stirling, David AllenAbstractThis two-day workshop, co-sponsored by NICEATM and IABS-NA, brought together over 60 international scientists from government, academia, and industry to advance alternative methods for human and veterinary Rabies Virus Vaccine (RVV) potency testing. On day one, workshop presentations focused on regulatory perspectives related to in vitro potency testing, including recent additions to the European Pharmacopoeia (5.2.14) that provide a scientific rationale for why in vivo methods may be less suitable for vaccine quality control than appropriately designed in vitro methods. Further presentations reviewed the role of the consistency approach to manufacturing and vaccine batch comparison to provide supportive data for the substitution of existing animal-based methods with in vitro assays. In addition, updates from research programs evaluating and validating RVV glycoprotein (G) quantitation by ELISA as an in vitro potency test were presented. On the second day, RVV stakeholders participated in separate human and veterinary vaccine discussion groups focused on identifying potential obstacles or additional requirements for successful implementation of non-animal alternatives to the in vivo potency test. Workshop outcomes and proposed follow...

This study evaluated: (i) whether SINAN can be reliably used for rabies surveillance; (ii) if patients in Brazil are receiving appropriate PEP and (iii) the benefits of implementing the latest Wo rld Health Organization (WHO) recommendations on PEP. Analysing SINAN records from 2008 to 2017 reveals an average of 506,148 bite-injury patients/year [range: 437k -545k] in the country, equivalent to an incidence of 255 bite-injuries/100,000 people/year [range: 231–280]. The number of reports of bites from suspect rabid dogs generally increased over time. In most states, records from SINAN indicating a suspect rabid dog do...

Abstract Rabies is a neglected disease with an estimated annual mortality of 55,000 human deaths, affecting mainly low-income countries. Over 95% of these cases result from virus transmission through the bite of infected dogs and for this reason there is a real need for a cheap and effective rabies veterinary vaccine to be used in mass vaccination campaigns. In this work, we describe the establishment of a simple platform for the production of a virus-like particles based rabies vaccine using mammalian cells and roller bottles as culture system. Adherent cells were cultured during more than 15 days and VLPs were c...

Abstract Rabies is a viral zoonosis caused by negative-stranded RNA viruses of the Lyssavirus genus. It can affect all mammals including humans. Dogs are the main source of human rabies deaths, contributing up to 99% of all rabies transmissions to humans. Vaccination against rabies is still the sole efficient way to fight against the disease. Cell culture vaccines are recommended by World Health Organization (WHO) for pre and post exposure prophylaxis; among them Vero cell rabies vaccines which are used worldwide. In this work we studied the purification of inactivated rabies virus produced in Vero cells grown in ...

In this study, we developed an adjuvanted hydrogel-based pDNA nanoparticulate vaccine for rabies protection and immunocontraception. In vivo, we observed an immune response skewed toward a Th2 type, in contrast to the Th1 type in our previous pDNA study. The observation was verified by the IgG2a/IgG1 ratio (

Hey everyone! I recently got hired at a small animal clinic after having interned there for about 2 months. I know that many vets and RVTs have their rabies pre-exposure vaccine and I was wondering if I should consider getting it. I will only be working at the clinic for a few months because I have to go back to school so I just didn't know if I should get it or wait for a few years. I'm definitely a slight hypochondriac and during my internship I have been scratched by a handful of cats... Should I get the rabies pre-exposure vaccine?
