Comparison of Immune Responses following Intradermal and Intramuscular Rabies Vaccination Methods
Authors
Abstract:
Rabies is a zoonotic viral disease. The causative agent is a negative-sense RNA genome virus of the genus Lyssavirus (Family: Rhabdoviridae). The disease, commonly transmitted by rabid dogs, is the cause of mortality of over 59000 humans worldwide annually. This disease can be prevented before the development of symptoms through proper vaccination even after exposure. Hence, improvement of the vaccination schedule in the countries where rabies is endemic is essential. In addition to the type of vaccine, injection routes also contribute to enhanced immune responses and increased potency of the vaccines. The vaccines approved by the World Health Organization (WHO) include cell culture and embryonated egg-based rabies vaccines (CCEEVs). In order to develop a vaccine against rabies, it is necessary to use an appropriate delivery system to promote a proper antigen-specific immune response. Different routes of injection such as intradermal (ID), intramuscular (IM) or subcutaneous (SC) are practiced, with controversies over their suitability. In this article, we discuss the immunological aspects of rabies vaccination by comparing ID and IM delivery systems.

Cellular immune response following pre-exposure and postexposure rabies vaccination by intradermal and intramuscular routes
PURPOSE Immunization against rabies in humans induces protective neutralizing antibodies; however, the induction of type 1 or type 2 cytokine mediated cellular immune responses following rabies vaccination is not understood. Hence, the present study investigated cellular cytokine responses in vaccinated individuals. MATERIALS AND METHODS The study groups included healthy rabies antigen naive ...

Rabies is a virtually 100% fatal acute viral encephalitis caused by an RNA virus belonging to family Rhabdoviridae and genus Lyssavirus. The virus can infect all warm blooded animals. The disease is transmitted to humans by the bite, lick or scratch of an infected animal. More than 99% of all human rabies deaths occur in the developing world. It is preventable with timely and proper usage of mo...

Immunogenicity of low dose intradermal hepatitis B vaccine and its comparison with standard dose intramuscular vaccination.
OBJECTIVE A prospective study was carried out in the well baby and immunization clinics of tertiary care hospital to compare the immunogenicity of low dose hepatitis B vaccine (HBV) given intradermally versus standard dose given intramuscularly. METHODS One hundred ninety six term, healthy, Australia antigen negative and exclusively breast fed babies were allocated into two groups in a simple...

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولIntradermal route for rabies vaccination should be generalized in travelers.
TO THE EDITOR—We agree with Wieten and colleagues [1] that an abbreviated intradermal (ID) schedule would greatly reduce preexposure rabies vaccination cost, including for travelers [2, 3]. However, because lyophilized vaccines do not contain a preservative, once reconstituted, an ampoule must be kept in a refrigerator at <8°C and used within 8 hours. Therefore, for this approach to be costeffe...
