We performed an abbreviated prospective study of rabies pre-exposure (PREP) vaccination in 109 volunteers. Group 1, the control group, received the conventional 3 intradermal injections on days 0, 7 and 21. Group 2 received one rabies vaccine injection (0.1 ml intradermally) at 2 sites on a single day. Group 3 was given one full ampule intramuscularly. One year later, all 3 groups received booster injections (0.1 ml at 4 sites) intradermally at one time or 2 injections intramuscularly on days 0 and 3. All subjects achieved a vigorous anamnestic antibody response 7 days after the boosters. These data suggest that one time immunization of one full dose intramuscularly or 2 site injections of 0.1 intradermally on a single day are adequate to prime immune memory and obtain an accelerated immune response one year later.

- "However, where feasible, due to a high turnover of animal bite victims, local health clinics, and well trained staff, switching from IM to ID immunization will make rabies PEP more accessible and affordable (Hampson et al. 2011). Besides alternative routes, shorter vaccine schedules are envisioned, based in part upon the evidence provided in animal models, the basic immunological response to rabies vaccines, epidemiological investigations, and human clinical trial data (Khawplod et al. 2012; Robertson et al. 2010; Rupprecht et al. 2009, 2010).

ABSTRACT: Rabies is one of the oldest known zoonoses. Recognized etiological agents consist of at least 15 proposed species of lyssaviruses with primary reservoirs residing in the Orders Carnivora and Chiroptera. A plethora of viral variants, maintained by a diverse set of abundant hosts, presents a formidable challenge to a strict concept of true disease eradication. Despite the availability of affordable and efficacious animal and human vaccines, today however dog rabies continues to escalate unabated across much of Asia and Africa, causing millions of suspect human exposures and tens of thousands of human rabies deaths annually. By identifying what hampers global human rabies elimination this chapter emphasizes that, given the global epidemiology of rabies, the “One Health” concept is key to solving the problem. Next to state of the art human rabies prevention, immunization and experimental therapy, it is obvious that human rabies can only be eliminated through rabies control at the animal source. This ‘paradigm shift’, however, needs new grassroot initiatives as well as political will and the closing of ranks of all stakeholders in the near future.Zoonoses - Infections Affecting Humans and Animals, 01/2015: pages 527-571; , ISBN: 978-94-017-9456-5

ABSTRACT: Using the principle of immunochromatography, we previously developed a method called RAPINA (Rapid Neutralizing Antibody detection test) that can measure the level of rabies virus -neutralizing antibody (VNA) in serum samples [Shiota S, Mannen K, Matsumoto T, Yamada K, Yasui T, Takayama K, et al. Development and evaluation of a rapid neutralizing antibody test for rabies. J Virol Methods 2009;161:58-62]. RAPINA is faster, simpler, and easier to perform compared with a virus-neutralizing test or enzyme-linked immunosorbent assay (ELISA). The improved version of RAPINA has greater positive and negative predictive values corresponding to a VNA level of 0.5 IU/mL, as recommended by the World Health Organization and the World Organization for Animal Health. To verify the efficacy of this improved method, serum samples were collected from humans and dogs before and after immunization against rabies and were tested in Japan, Sri Lanka, and Thailand. The results were compared between RAPINA and the true VNA levels measured by the Rapid Fluorescent Focus Inhibition Test (RFFIT). The improved RAPINA accurately predicted seropositivity for 182 of 183 seropositive human samples as assessed by RFFIT (99.5%) and for 138 of 140 RFFIT-negative human samples (98.6%). In dog serum samples, the positive and negative predictive values were 99.7% (345/355) and 95.6% (174/182), respectively. RAPINA was also used to estimate VNA levels in a semiquantitative manner by using serial dilution of serum samples. Our results show that RAPINA is an easy and rapid method for measuring VNA levels before and after immunization with the rabies vaccine and does not need a high skill level or sophisticated equipment. RAPINA can be used to monitor the success of preexposure prophylaxis in at-risk persons, vaccine coverage, and animal control. It can also be used in laboratories with modest facilities and where a large number of samples are screened.Vaccine 04/2012; 30(26):3891-6. DOI:10.1016/j.vaccine.2012.04.003 · 3.62 Impact Factor
