Public Health Agency of Canada. Post-exposure prophylaxis should begin immediately following exposure to a wild terrestrial carnivore (such as a fox, skunk or raccoon) in enzootic areas, unless the animal is available for rabies testing and rabies is not considered likely. Petting a rabid animal or handling its blood, urine or feces are not considered exposures. The Fuenzalida-Palacios rabies vaccine has been used in South America for rabies post-exposure prophylaxis. The Public Health Agency of Canada's National Microbiology Laboratory (NML) is the Canadian rabies reference laboratory. If an alternative vaccine is not available, post-exposure prophylaxis using PCECV should be administered to a person with a hypersensitivity to egg with strict medical monitoring. Bites of squirrels, chipmunks, rats, mice, hamsters, gerbils, guinea pigs, other small rodents, rabbits and hares would only warrant post-exposure rabies prophylaxis if the behaviour of the biting animal was highly unusual. When PCECV was administered according to the recommended immunization schedule, 100% of subjects attained an adequate antibody titre by Day 28 or earlier. Rabies is transmitted only when the virus is introduced into a bite wound, open cuts in skin, or onto mucous membranes such as the mouth or eyes. For post-exposure prophylaxis of immunocompetent persons previously unimmunized with rabies vaccine, four 1.0 mL doses of HDCV or PCECV should be administered IM. Care should be taken to clean the wound to its full depth. Once initiated, rabies prophylaxis should not be interrupted or discontinued because of local or mild systemic adverse reactions to rabies vaccine. The existing titre of rabies antibodies should be determined and expert opinion in the management of these individuals should be sought promptly. Refer to Principles of Vaccine Interchangeability in Part 1 for additional general information. Determination of antibody response is also advisable if post-exposure vaccination is given to those whose immune response may be reduced by illness or medication. In 2006, the CFIA tested 2,150 bats, 3.3% of which were positive. Refer to Post-exposure prophylaxis of previously immunized individuals for information on the post-exposure management of these individuals. Transmission rarely occurs from non-bite exposures. For hematopoietic stem cell transplant recipients, pre-exposure rabies vaccination can be started 6 to12 months after transplant. Almost any mammal that has been exposed to an infected bat may become infected. For specific advice, consult an allergy specialist. At first indication of rabies in the animal, arrange to have the animal tested for rabies. All medicines and vaccines have side effects. 5 Physicians at the US Centers for Disease Control and Prevention (CDC) … Rabies vaccine and RabIg may be given at the same time but at different injection sites, using separate needles and syringes. When a vaccinated cat encounters these agents in the future, it rapidly generates antibodies and activates the cells that recognize the agents, producing an immune response that results in the elimination of the invading agent. PCECV (RabAvert®) should be store at +2°C to +8°C and protected from light. The species most commonly identified as having rabies by region, based on total numbers of positive test results, were as follows: foxes in the Northwest Territories and Nunavut Territory (70%), skunks in Manitoba (75%) and Saskatchewan (70%), and bats in British Columbia (99%), Alberta (81%), Quebec (70% since 2008 when raccoon rabies was last detected) and Ontario (56%); In Ontario, the second most affected species was skunks (27%). This copyrighted material has been downloaded from a licensed data provider and is not for distribution, except as may be authorized by the applicable terms of use. Usually such reactions can be successfully managed with anti-inflammatory and antipyretic agents. Adverse reactions are reported on suspicion and the reports describe events that have occurred after vaccination. If the site of the wound is unknown, the entire dose should be administered intramuscularly at a separate site from the administration of rabies vaccine. A veterinarian should be consulted to determine if the animal is up-to-date with its vaccinations. History of household exposure to a bat: 16.7%, * NACI has not yet deliberated on the use of KamRAB™ or HyperRAB®. A small number of rabid raccoons were also found in Manitoba and Saskatchewan. Analysis conducted in Canada estimated that a case of human rabies related to bedroom exposure to a bat (i.e., finding a bat in the room of a sleeping person with no recognized physical contact with the bat) is expected to occur in Canada once every 84 years. At first indication of rabies in the animal, give. A more detailed description of the clinical signs of rabies in animals is available at: Fact Sheet: Rabies. There is no evidence that interference occurs with antimalarial drugs other than chloroquine. To help prevent over-vaccination, a set of guidelines for both … Informed Consent Action Network. The virus is easily killed by sunlight, soap and drying. Thats because they may start within a week but can last much longer. Adverse reactions to vaccines were examined in 311 canine cases reported to the Ministry of Agriculture, Forestry and Fisheries in Japan during the period of 6 years from April of 1994 to March of 2000, and classified according to their clinical symptoms. The risk of rabies must be carefully considered before a decision is made to discontinue immunization. Post-exposure vaccination should never be postponed. Touria Izri Videojournalist @TouriaIzri Contact. Pre-exposure rabies immunization with either HDCV or PCECV should be offered to people at high risk of close contact with rabid animals or the rabies virus, for example: Rabies prophylaxis must be considered in every incident in which human exposure to potentially rabid animals has occurred, unless rabies is known to be absent from the local animal population. Expert opinion should be sought in the management of these individuals. Severe allergic reactions to Pfizer's COVID-19 vaccine were rare in the first 10 days of its rollout, with 21 cases among nearly 1.9 doses, the CDC reported. The length of time virus may be excreted in saliva before the development of symptoms (asymptomatic carriage) has not been determined for the purpose of defining rabies exposure except in dogs, cats and ferrets. It happens when some dogs' immune systems are overloaded and unable to deal with the vaccine(s) appropriately. When the rabies virus is inoculated into a wound, it must be taken up at a nerve synapse to travel to the brain, where it causes fatal encephalitis. Post-exposure prophylaxis with two doses of, Documentation of a complete course of pre-exposure or post-exposure prophylaxis with HDCV or PCECV, OR, Documentation of complete immunization with other types of rabies vaccine, or with HDCV or PCECV according to unapproved schedules, with the demonstration of an acceptable concentration of neutralizing rabies antibody in serum after completion of the series. If illness suggestive of rabies exists at the time of the bite or develops during the observation period, the animal should be humanely euthanized in a way that does as little damage to the brain as possible, and the head submitted for laboratory examination and rabies testing. If these animals - are alive and healthy at the end of the 10-day period, they would not have transmitted rabies in their saliva at the time of the bite. People who require a booster dose of rabies vaccine can be given PCECV or HDCV, regardless of the vaccine used for the initial vaccination series. Consult appropriate public health and CFIA officials. Headache and low-grade fever may follow administration of RabIg. Because these small animals are not known to have caused human rabies in North America, post-exposure prophylaxis should be considered only if the animal's behaviour is highly unusual. Side Effects. NML conducts testing on serum and cerebrospinal fluid samples from all provinces and territories in Canada with the exception of Ontario, where serological testing is performed by the Public Health Ontario Laboratory (PHOL). Pre-exposure rabies immunization should be offered to workers at high risk of occupational exposure to potentially rabid animals or to the rabies virus. In Canada and the US, foxes, skunks, raccoons and bats may be reservoirs capable of transmitting infection to dogs, cats, livestock and people. Rabies is a rare viral central nervous system infection most often transmitted to humans through the bite of an infected mammal. Vaccine should be administered IM into the deltoid muscle in older children and adults or into the vastus lateralis muscle (anterolateral thigh) in infants, but never in the gluteal region as this may result in decreased response to the vaccine. they should not be decapitated. Once the bat has been captured, local public health officials should be contacted. The more common, agitated (furious) form presents with the classic symptoms of hydrophobia and aerophobia (severe laryngeal or diaphragmatic spasms and a sensation of choking when attempting to drink or when air is blown in the face) with a rapidly progressing encephalitis and death. Over the same time period, skunks accounted for 37% of reported cases, followed by bats (33%), raccoons (9%) and foxes (6%). Post-exposure prophylaxis is ineffective after the rabies virus invades the nervous system. Even the reports of severe adverse reactions that can be either life-threatening or lead to permanent disability, such as neuroparalytic accidents, are few, and a detailed analysis of a … The recent unfortunate rabies transmissions through solid organ transplants of an infected donor in Germany required the initiation of a vaccination program to protect health care workers (HCWs) with close contact to rabies-infected patients. Lymphadenopathy, nausea and rash have been reported occasionally. In my years of practice I’ve witnessed all of the rabies vaccine reactions I’ve listed below. HDCV (IMOVAX® Rabies) should be store at +2°C to +8°C, and should not be used if it has been frozen. This is a histogram that identifies that there was one death from rabies in 1925, 1926 1931, 1933, 1944, 1964, 1967, 1970, 1977, 1984, 1985, 2000, 2003, 2007. Population and Public Health Branch. The animal should be observed by a public health official or veterinarian at the end of the 10-day observation period to ensure that it is alive and healthy. Dogs, cats and ferrets that are apparently healthy should be confined and observed for 10 days after a bite, regardless of the animal's rabies vaccination status. Nova Scotia reported 3 cases, New Brunswick 2 cases and Prince Edward Island 1 case. The known adverse reactions of the vaccines are listed in the product information. Anaphylactic (or allergic) reactions are amongst the most severe reactions that can be seen after vaccination. The decision should consider several factors, including the rate of occurrence of rabies in the area, if it was a domestic or stray animal, the type of exposure, the circumstances of the exposure, including whether it was a provoked or unprovoked exposure, and the severity and location of the wound. The use of the proper syringe and needle is essential to ensure that the correct route and dose are used. Because of the excellent immune response to rabies vaccine, healthy people immunized with an appropriate regimen do not require routine antibody determinations after either pre-exposure or post-exposure rabies vaccination, unless one of the following applies: People with ongoing high risk of exposure to the rabies virus or potentially rabid animals require periodic serological testing to ensure the persistence of circulating antibodies. If it is possible to avoid exposure to rabies, pre-exposure immunization should be deferred in immunocompromised people until they are no longer immunocompromised. Rabies is a disease of mammals, both domestic and wild. The ID route should not be used in persons who are immunocompromised due to illness or medication, or are taking chloroquine, as the immune response to the vaccine may not be protective under these circumstances. A study from the United States found that severe allergic reactions to Moderna's COVID-19 vaccine is "rare". The RabIg provides immediate passive protection until the exposed person mounts an immune response to the rabies vaccine. Adverse reactions for rabies vaccines include injection site reactions, such as pain, erythema, swelling and itching. In these individuals, vaccine should be administered by the IM route only. Generally, rabies is less likely in domestic animals, particularly domestic dogs, compared to stray animals, due to the following factors: domestic animals are more likely to be vaccinated; and domestic animals may spend less time outdoors where exposure to a potentially rabid animal could occur. Following vaccination, neutralizing antibodies begin to develop within seven days and persist for at least two years. The manifestations of rabies and the incubation periods vary in different species. Any remaining volume of RabIg should be injected intramuscularly, using a separate needle, at a site distant from the site of vaccine administration. This precaution is not known to apply to other antimalarial drugs. Anaphylaxis. Though the connection remains inconclusive, Floridians report adverse reactions from the COVID vaccine that range from headaches to chest pains to cardiac arrest. Drug information provided by: IBM Micromedex. If rabies immunoglobulin is administered, this may interfere with the response to live vaccines. If the dog, cat or ferret has escaped, attempts should be made to find the animal and owner. Rabies incidence rates are similar in Canada and the US and are reported in cases per billion person-years because of the extremely low number of cases. The number of rabid animals detected in Canada has decreased considerably from 670 in 2000 to 145 in 2009. Centers for Disease Control and Prevention. This factor should be considered when determining the appropriate post-exposure management. Recent cases have been due to bat exposures. ANKARA. Rabies may be transmitted to domestic pets during exposure to rabid wild or outdoor animals. Transcript for First US report of serious adverse vaccine reaction Of course, there is concern tonight over efforts to get that vaccine out and across the country, even as a major storm bears down. Here is information from Dr. Richard Ford: “In veterinary medicine, there is no mandate to report a vaccine adverse reaction, whether the reaction is known to have been caused by a vaccine or merely suspected to have been. Of these 36 bat-related human cases, the types of exposures reported were as follows: Figure 1: Rabies - Number of Deaths in Canada, 1924-2009. Pregnancy and breastfeeding are not contraindications to post-exposure rabies prophylaxis, but it is prudent to delay pre-exposure immunization of pregnant women unless there is a substantial risk of exposure. Every vaccination increases the risk of an adverse vaccine reaction happening to your dog. HDCV or PCECV administered at the same time as RabIg (using a separate needle, syringe and injection site) and local treatment are highly effective in preventing rabies in exposed individuals. If the suspect animal is a dog, cat or ferret that is healthy and available for observation, post-exposure prophylaxis may be withheld, pending the animal's status after a 10-day observation period. Immediate and thorough cleaning and flushing of the wound with soap and water is imperative and is probably the most effective procedure in the prevention of rabies. Bites on the hands and face, because of the density of nerve endings, are considered higher-risk exposures. Wherever possible, an immunization series should be completed with the same product. Based on expert opinion, live vaccines given by nasal or oral route and essential inactivated vaccines, may be administered at the same time as rabies vaccines. Refer to Immunization in Pregnancy and Breastfeeding in Part 3 for additional general information. In addition to the vaccination site, … An unexpected AEFI is an event that is not listed in available product information but may be due to the immunization, or a change in the frequency of a known AEFI. Even though the adverse reactions are unpleasant to individual dogs and their owners, the benefits of oral rabies vaccination clearly outweigh the risks. Had an allergic reaction to a previous dose of rabies vaccine; Are allergic to any component of the vaccine (e.g., neomycin, phenol) Are ill with an infection or fever; Are pregnant, unless specifically advised by a doctor; Tell your healthcare provider about any allergies, medications you are taking, illnesses or any previous suspected reactions to any vaccine, since they might … However, for pre-exposure vaccination, an alternative vaccine, HDCV, should be used in vaccinees with a history of hypersensitivity reactions to egg or egg products. Healthcare providers who observe or treat an anaphylactic episode are asked to complete a worksheet in addition to the AEFI form. Neither Moderna's nor Pfizer's clinical trials found that the vaccine caused severe adverse events such as anaphylaxis. Rotavirus61 None reported to WHO – To date, post-licensure surveil - lance does not indicate any increased risk of intussusception or other serious adverse reaction associated with the use of current rotavirus vaccines. Expected rates of vaccine reactions have been included if available in published literature. Raccoon rabies arrived in Canada from the US in 1999 and was found mainly in Ontario, New Brunswick, and Quebec. A rabies vaccine reaction can cause serious problems, but any vaccine has the potential to cause a reaction. Pregnancy is not a contraindication to post-exposure prophylaxis with rabies vaccine and RabIg, but it would be prudent to delay pre-exposure immunization of pregnant women, unless there is a substantial risk of exposure. For this vaccine, about 20% of people complain of redness at the injection site or a sore arm. As a side effect, dog vaccinations can create chronic health issues including allergies, digestive upset, behavior issues, joint pain and most other inflammatory, auto-immune problems. A systematic follow-up of adverse effects was initiated. Laboratory workers who handle the rabies virus. The person responsible for observation of the animal should be advised to notify public health officials if the animal becomes ill or escapes during the observation period. The worker should use extreme caution to ensure that there is no further exposure to the bat. In a child, a bat landing on clothing could be considered a reason for intervention, as a history to rule out a bite, scratch or mucous membrane exposure may not be reliable. The history obtained from a child may be difficult to interpret and, potentially, unreliable. Several reporting systems have been established to monitor adverse events following immunization. Unvaccinated animals that remain healthy should be vaccinated at the end of the observation period. If the incident involves a dog or cat, determining if it is a stray or domestic animal assists with the risk assessment. Heather says: January 9, 2021 at 4:28 am. The person is at ongoing high risk of exposure to rabies. When more than one wound exists, each wound should be locally infiltrated with a portion of the RabIg using a separate needle. These complications include autism (measles vaccine), multiple sclerosis (hepatitis B vaccine), meningoencephalitis (Japanese encephalitis vaccine), Guillain-Barré syndrome and giant cell arteritis (influenza vaccine), and reactions after exposure to animal rabies vaccine. Post-exposure prophylaxis is highly effective in preventing rabies. Post-vaccination serology is recommended: after pre-exposure immunization using the ID route; following immunization of immunocompromised individuals or people taking chloroquine; or if there has been a significant deviation from the recommended vaccination schedule. A map of the areas where rabies transmission occurs is available from the World Health Organization (WHO) website: Rabies countries or areas at risk. Some guidelines also suggest the application of a viricidal agent, such as iodine-containing or alcohol solutions. This is in addition to the RabIg as discussed above. They also comprise details of mild and severe adverse reactions (local and systemic) following immunization. WebMD does not provide medical advice, diagnosis or treatment. These small animals can, theoretically, become infected by bat strains of rabies; however, no cases of transmission of bat strains of rabies from these animals to humans have been documented. The virus may enter a nerve rapidly or it may remain at the site of the bite for an extended period before gaining access to the nervous system. Facilities for emergency treatment of anaphylactic reactions should be available. Vaccines that seem to be most likely to cause reactions include the killed rabies, canine corona, FeLV, and Leptospira vaccine. Bats should be submitted intact for rabies testing, i.e. The rabies vaccine and RabIg should be given at different anatomical sites on day 0, using a separate needle and syringe. Bites from an infected animal are the main route of exposure. Two of these cases of rabies have been attributed to probable aerosol exposures in laboratories, and two cases have been attributed to possible airborne exposures in caves containing millions of bats; however, alternative infection routes cannot be discounted in several of these cases. Other times they only show up weeks later. This table and accompanying text are guides for management and do not replace clinical judgment. If the initiation of post-exposure prophylaxis is delayed until test results from the involved animal are available, a maximum waiting period of 48 hours is recommended. Refer to Contents of Immunizing Agents Available for Use in Canada in Part 1 for a list of vaccines and passive immunizing agents available for use in Canada and their contents. Centers for Disease Control and Prevention. These recommendations are intended as a guide and may need to be modified in accordance with the specific circumstances of the exposure. Temporally associated neurologic events have also been very rarely reported but causal association with vaccination has not been established. Rabies virus is readily demonstrable in brains of animals with neurologic symptoms. The immunogenicity of PCECV and HDCV for pre-exposure vaccination has been demonstrated in clinical trials. Any animal that has bitten a human or is suspected of being rabid should be reported to local public health officials. Three doses of HDCV or PCECV are required and should be given on days 0, 7 and any time between days 21 to 28. Between Dec. 14 and Dec. 23, 21 cases of anaphylaxis were submitted to the Vaccine Adverse Event Reporting System after administration of a … How prevalent is rabies in the involved species in the geographic area? Rabies in these animals is rare in Canada with only three rabid ground hogs (woodchucks) detected from 1998 to mid-2011, two in Manitoba in 1999 and one in Ontario in 2000. Persons with a proven history of hypersensitivity to the vaccine or any component of the vaccine or its container should not be given the vaccine for pre-exposure immunization if possible. The species of animal, including the prevalence of rabies in that species and the prevalence of rabies in other species in the area. RabIg should not be repeated at the initiation of this second course. Persistence of adequate antibody titres for up to 2 years after immunization with PCECV has been demonstrated. Definition: The USDA considers a vaccine adverse event to be any undesirable side effect or unintended effect (including lack of desired result) associated with the administration of a licensed biological product (i.e., a vaccine). Exposures occurring in the course of caring for humans with rabies could, theoretically, transmit the infection. The reports of scratches consist of a facial scratch from a bat in 1985 and a scratch from a rabid calf in the 1940s. In 2004, the US Centers for Disease Control and Prevention confirmed the first reported case of rabies following solid organ transplantation. Local injection site pain, erythema and induration are commonly reported following administration of RabIg, as are systemic reactions such as headache and low-grade fever. Between 1924 and 2009, 24 people in six provinces died of rabies (Figure 1): Quebec (12), Ontario (6), Saskatchewan (2), Alberta (2), British Columbia (1) and Nova Scotia (1). Hunter and trappers in areas with confirmed rabies. Refer to Contraindications, Precautions and Concerns in Part 2 for additional information. RabIg is a solution of anti-rabies Ig for IM administration, prepared from the pooled human plasma of screened donors immunized with rabies vaccine. Individuals who engage in activities such as hunting and trapping or cave exploration (spelunkers) that place them in close contact with potentially rabid animals, such as bats, foxes, skunks and raccoons, in areas where rabies is found, may also be considered at higher risk of rabies exposure. Expected rates of vaccine reactions have been included if available in published literature.
