Evaluation of Thimerosal on the Potency and Stability of Inactivated Animal Rabies Vaccine @inproceedings{Ahmadnejad2019EvaluationOT, title={Evaluation of Thimerosal on the Potency and Stability of Inactivated Animal Rabies Vaccine}, author={F. Ahmadnejad and N. Miandehi and A. Gholami and M. Chehrazi and Saeed Jodairi Eslami and Ali Moradi-Joshaghan and Zohreh Parhizkar and … Thimerosal is an ethyl mercury-based preservative used in vials that contain more than one dose of a vaccine (multi-dose vials) to prevent germs, bacteria and/or fungi from contaminating the vaccine. Thimerosal is a mercury-based preservative which is nearly 50% mercury by weight. [9] Three doses of the vaccine are given over a one-month period on days zero, seven, and either twenty-one or twenty-eight. In 1979, the Van Houweling Research Laboratory of the Silliman University Medical Center in Dumaguete in the Philippines[22] developed and produced a dog vaccine that gave a three-year immunity from rabies. [6] Other groups may include veterinarians, researchers, or people planning to travel to regions where rabies is common. People who are exposed to mercury at levels above limits set by federal agencies such as the FDA and the EPA run the risk of mercury poisoning. [6] About 35 to 45 percent of people develop a brief period of redness and pain at the injection site, and 5 to 15 percent of people may experience fever, headaches, or nausea. PRODUCT DESCRIPTION: Defensor 3 is for vaccination of healthy dogs, cats, ferrets, cattle, and sheep 12 weeks of age or older as an aid in preventing rabies. The most dangerous substances that some vaccines contain are thimerosal, aluminum, formaldehyde, and mercury. [6] They can be used to prevent rabies before, and for a period of time after, exposure to the rabies virus, which is commonly caused by a dog bite or a bat bite. Merial makes a thimerosal-free rabies vaccine called IMRAB 3 TF (the 3 designates a 3-year vaccine, and TF stands for “thimerosal-free”). [30] Baits are usually distributed by aircraft to more efficiently cover large, rural regions. The successful program in the Philippines was later used as a model by other countries, such as Ecuador and the Yucatan State of Mexico, in their fight against rabies conducted in collaboration with the World Health Organization. [25] When an animal bites into the bait, the packets burst and the vaccine is administered. Chiron's RabAvert rabies vaccine contains thimerosal Only the Injectable Bordetella and Rattlesnake vaccines contain Thimerosal as a preservative, as there is no alternative on the market. Yes, I want to get emails from Dogs Naturally. [6] Their use is thus not recommended by the World Health Organization. CCEEVs use inactivated rabies virus grown from either embryonated eggs or in cell cultures and are safe for use in humans and animals. CCEEVs can be used in both pre- and post-exposure vaccinations. While this was the dog’s third rabies booster and the two prior vaccines were thimerosal-free and had not elicited any AE, he … [28] ORV programs typically use edible baits to deliver the vaccine to targeted animals. Thimerosal is a very inflammatory neurotoxin and genetic mutator and Pittman Moore Animal Pharmaceutical Company warned against its safety “even in dog serum” to Eli Lilly Company in 1935. Most vaccines do not contain thimerosal. You'll need 3 doses of the vaccine, usually over a period of 28 days. Booster doses. Highly purified, inactivated virus used in vaccine production ; Smooth, easy subcutaneous or intramuscular injection (subcutaneous only for ferrets) 2,3 Inactivated vaccine containing > 2 I.U. [6] The purified Vero cell rabies vaccine uses the attenuated Wistar strain of the rabies virus, and uses the Vero cell line as its host. That said, there is no evidence that this causes any health problems, cf statements from The WHO , the FDA , and the EMEA . Despite this, Thimerosal is still used as a preservative in a staggering number of vaccinations for both humans and dogs. Company: Zoetis Rabies Vaccine. Lyme Disease Vaccine (Recombinant, non-adjuvanted)Bordetella – Injectable Vaccinend Parainfluenza)1st Care carries 100% Thimerosal-free vaccines standard for those that are available in this form. [27] ORV is a preventive measure to eradicate rabies in wild animal vectors of disease, mainly foxes, raccoons, raccoon dogs, coyotes and jackals, but also can be used for dogs in developing countries. The vaccine was given intramuscularly above the left shoulder. Merial IMRAB TF. Abstract Objectives: Thiomersal is ethylmercury containing compound. You can change your mind and unsubscribe anytime. [11] For people who have previously been vaccinated, only a single dose of the rabies vaccine is required. Thimerosal is added to vials of vaccine that contain more than one dose (multi-dose vials) to prevent growth of germs, like bacteria and fungi. [21], Aside from vaccinating humans, another approach was also developed by vaccinating dogs to prevent the spread of the virus. Fort Dodge makes a thimerosal-free rabies vaccine called RABVAC 3 TF (while it is not listed on their website, we did confirm with them that it is still available). Also contains Aluminium phosphate as an adjuvant. Vaccinations are often administered when owners take in their dogs for check-ups and visits at the vet. Nevertheless, the Public Health Service agencies, the American Academy of Pediatrics, and the vaccine manufacturers agreed that thimerosal should be eliminated from all pediatric vaccines, and the amount of thimerosal reduced in other vaccines. The vaccine is known as Rabisin (Mérial), which is a cell based rabies vaccine only used countrywide. [16] The treatment started with a subcutaneous injection on 6 July 1885, at 8:00 pm, which was followed with 12 additional doses administered over the following 10 days. There's also a vaccine for people at risk of being infected. [27] The effectiveness of ORV campaigns in specific areas is determined through trap-and-release methods. Please support the hard working holistic vets who make this information possible. [25] ORV programs were initiated in Europe in the 1980s, Canada in 1985, and in the United States in 1990. On this site, you will find information about vaccines that are … The rabies vaccine is a vaccine used to prevent rabies. [11] However, vaccination after exposure is neither a treatment nor a cure for rabies; it can only prevent the development of rabies in a person if given before the virus reaches the brain. Adenovirus, a common viral pathogen that infects the GI tract and causes diarrhea is genetically altered to express rabies surface proteins, thereby allowing the adenovirus to infect GI tract cells. [32][33], Imrab is an example of a veterinary rabies vaccine containing the Pasteur strain of killed rabies virus. You should consider getting vaccinated against rabies if you're travelling to an area of the world where rabies is common and: Therefore, two groups of rabies vaccine were produced. [7] Millions of people globally are vaccinated against the virus. A few companies are making Thimerosal-free canine rabies vaccines. [6], Rabies vaccines may be used safely by all age groups. Rabies vaccines are safe in all age groups. The seed virus is a highly immunogenic, fixed strain of rabies virus which originated from Louis Pasteur’s original isolate in 1882. Symptoms of mercury poisoning include: There has been concern that mercury poisoning in young children is a direct cause of autism and this link has also been shown in animal research. Merial makes a Thimerosol-free rabies vaccine called IMRAB 3 TF (the 3 designates a 3-year vaccine, and TF stands for “Thimersol-free”). There is also a 1 year version, IMRAB 1 TF. The rabies vaccines we insist upon are made by Boehringer Ingelheim (who bought Merial) and they are called IMRAB 1 TF or IMRAB 3 TF. Several different types of Imrab exist, including Imrab, Imrab 3, and Imrab Large Animal. 0.1 mg/ml Thiomersal are added as a preservative. [6], The first rabies vaccine was introduced in 1885 and was followed by an improved version in 1908. Rabies Vaccine: Rabies is a serious threat to cats and we require this vaccination for all of our feline patients. [6], Doses are usually given by injection into the skin or muscle. The TF stands for (thimerosal-free formulation). These rabies vaccine side effects usually disappear within a few days. Killed Virus. In fact, side effects of rabies vaccines in cats are very rare. Cost of the Rabies Vaccine for Dogs [6][15], Virtually all infections with rabies resulted in death until two French scientists, Louis Pasteur and Émile Roux, developed the first rabies vaccination in 1885. [14], In addition to these developments, newer and less expensive purified chicken embryo cell vaccines (CCEEV) and purified Vero cell rabies vaccines are now available and are recommended for use by the WHO. The content on this website is not meant to replace veterinary advice. Because of the difficult nature of their production, these vaccines are more expensive than the adjuvanted vaccines, particularly the 1 year and 3 year Rabies vaccines. The cost of the rabies vaccine continues to be a limitation to acquiring pre-exposure rabies immunization for travellers from developed countries. [6] Those at risk may have tests done to measure the amount of rabies antibodies in the blood, and then get rabies boosters as needed. [6] A long-lasting immunity to the virus develops after a full course of treatment. Rabies vaccination. This enables the viral vector to infect cells in the GI and stimulate a cellular and humoral response that would provide immunity in the case of being bitten by an infected animal and being infected via blood. It is possible and more cost-effective to split one intramuscular dose of the vaccine into several intradermal doses, but this practice is discouraged by American health authorities. [18] Neural tissue vaccines also carry a certain risk of neurological complications. [19], When the modern cell-culture rabies vaccine was first introduced in the early 1980s, it cost $45 per dose was considered to be too expensive. Millions of people globally have been vaccinated and it is estimated that this saves more than 250,000 people a year. About 35 to 45 percent of people develop a brief period of redness and pain at the injection site, and 5 to 15 percent of people may experience fever, headaches, or nausea. There is also a 1-year version, IMRAB 1 TF. For use in dogs, cats, ferrets, cattle, and sheep only. Pittman Moore found that over 50% of vaccinated dogs suffered inflammatory reactions to Thimerosal. [17], The Pasteur-Roux vaccine attenuated the harvested virus samples by allowing them to dry for five to ten days. IMRAB 1 TF (thimerosal-free) provides one year of rabies protection for dogs and cats 5; IMRAB has been widely used for more than 30 years — with millions of animals protected against rabies 1. Recommended for use in healthy dogs, cats and ferrets 3 months of age or older. [29] By immunizing wild or stray animals, ORV programs work to create a buffer zone between the rabies virus and potential contact with humans, pets, or livestock. Answer: You can pre-treat dogs with the oral homeopathics, Thuja and Lyssin, to help blunt any adverse effects of the rabies vaccine. Because of the certain fatality of the virus, receiving the vaccine is always advisable. Thimerosal is a mercury-based preservative which is nearly 50% mercury by weight. Chiron is among defendants in class action lawsuit filed in Louisiana regarding the alleged link between the vaccine additive thimerosal and autism, SEC filing states. These safety issues were raised in Congressional testimony several times and the correspondence from Pittman Moore to Eli Lilly is a part of Congressional Hearings testimony on the dangers of mercury in vaccines. Rabies – given 3-4 weeks apart from other vaccines Mercury-free (thimerosal-free) 16-18 months (1 year after last puppy vaccines) Distemper + Parvovirus, MLV (or test titer levels) 16-18 months (1 year after puppy vaccine) Rabies – give 3-4 weeks apart from other vaccines mercury-free (TF) [23], In Tunisia a rabies control program was initiated to give dog owners free vaccination to promote mass vaccination which was sponsored by their government.

Flu vaccines in multi-dose vials contain thimerosal to safeguard against contamination of the vial. If you’d like more on how we use your information, just check out our Privacy Policy. [12], Rabies vaccines are safe in all age groups. As a result, there was speculation that the thimerosal in vaccines may be connected to autism; however, an Institutes of Medicine report failed to substantiate these claims. Committee to Advise on Tropical Medicine and Travel (CATMAT). Material Name: Rabies Vaccine, Killed Virus Austria OEL - MAKs 5 mg/m3 Version: 2.0 Germany (DFG) - MAK 4 mg/m3 1.5 mg/m3 Page 3 of 8 Latvia OEL - TWA 6 mg/m3 Aluminum hydroxide gel ACGIH Threshold Limit Value (TWA) 1 mg/m3 Revision date: 14-Jan-2014 The vaccine is prepared from cell-culture-grown, chemically inactivated rabies virus. Dana has been a raw feeding, natural rearing breeder since the 90's and is a sought after speaker and outspoken advocate for natural health care for dogs and people. [29] The idea of wildlife vaccination was conceived during the 1960s, and modified-live rabies viruses were used for the experimental oral vaccination of carnivores by the 1970s. [27] Current research suggests that if adequate amounts of the vaccine is ingested, immunity to the virus should last for upwards of one year. ... Mercury is found in Thimerosal, a preservative used in multi-dose vaccine vials. [medical citation needed], Group of vaccines against infection of humans and animals with the rabies virus, It may require cleanup to comply with Wikipedia's content policies, particularly, World Health Organization's List of Essential Medicines, Learn how and when to remove this template message, "Rabies vaccine, human diploid cell (Imovax Rabies) Use During Pregnancy", "Rabies Vaccine BP - Summary of Product Characteristics (SmPC)", "Rabipur pre-filled syringe - Summary of Product Characteristics (SmPC)", "Imovax Rabies (rabies virus strain pm-1503-3m antigen- propiolactone inactivated and water kit", Centers for Disease Control and Prevention, "An Advisory Committee Statement (ACS). [6] After exposure, the vaccination is typically used along with rabies immunoglobulin. Similar nerve tissue-derived vaccines are still used in some countries, and while they are much cheaper than modern cell culture vaccines, they are not as effective. [20], Pre-exposure immunization has been used on domesticated and wild populations. When they do happen, they include slight fever, lethargy, decreased appetite and a localized swelling at the vaccine site. [31] ORV programs have seen success in preventing the westward spread of raccoon variant rabies in the United States and even eradicating rabies in red foxes in Switzerland. [27] The potential for human contact with baits is a present concern for OPV programs, but the oral vaccine does not contain the whole rabies virus and has been proven safe in over 60 animal species including cats and dogs. [6], Immunity following a course of doses is typically long lasting, and additional doses are usually not needed unless the person has a high risk of contracting the virus. In order to place baits more precisely and to minimize human and pet contact with baits, however, they are distributed by hand in suburban or urban regions. [6], The human diploid cell rabies vaccine (H.D.C.V.) The results indicated that thimerosal has no deleterious effect on the vaccine; furthermore, its elimination did not influence the potency and stability of the vaccine. Fort Dodge makes a Thimerosol-free rabies vaccine called RABVAC 3 TF. [6] Because of the certain fatality of the virus, receiving the vaccine is always advisable.

The rabies vaccination is usually paid for separately, and it costs approximately $20 to $30. In addition, some international travelers might be candidates for pre-exposure vaccination if they are likely to come in contact with animals in areas where dog or other animal rabies is enzootic and immediate access to appropriate medical care, including rabies vaccine and immune globulin, might be … ORV baits consist of a small packet containing the oral vaccine which is then either coated in a fishmeal paste or encased in a fishmeal-polymer block. Fortunately, reactions to vaccines are very uncommon in cats. Dana works tirelessly to educate pet owners so they can influence veterinary medicine and change current vaccine, food and preventive health practices. [30] Titer tests are performed on the blood drawn from the sample animals in order to measure rabies antibody levels in the blood. Thimerosal was present in the vaccines within a narrow range of 47.4 ± 0.4 to 53.7 ± 0.7 µg per dose (0.5 mL vaccine), in agreement with product information, except for the influenza vaccine from one of the producers, for which the thimerosal mass per dose was below the detection limit. [34][35] The reason why these oral vaccines that enter the body through the GI tract are able to convey resistance to rabies is due to the usage of a live human adenovirus type 5 vector. Thimerosal is a mercury compound included in vaccines as a preservative to prevent bacterial growth in the product. Thimerosal was first introduced in vaccines by Eli Lilly in the 1930s. [6] Rabies vaccines are effective in humans and other animals, and vaccinating dogs is very effective in preventing the spread of rabies to humans. Nine-year-old Joseph Meister (1876–1940), who had been mauled by a rabid dog, was the first human to receive this vaccine. INDICATIONS: Approved for the vaccination of healthy dogs, cats and ferrets as an aid in preventing rabies. [9] Following administration of a booster dose, one study found 97% of immunocompetent individuals demonstrated protective levels of neutralizing antibodies after ten years. Human diploid cell rabies vaccines are inactivated vaccines made using the attenuated Pitman-Moore L503 strain of the virus. Nobivac®3-Rabies vaccine is for vaccination of healthy dogs, cats, ferrets, cattle and sheep as an aid in preventing rabies. In 2015 in the United States, a course of three doses could cost over $1,000, while in Europe a course costs around €100. [8], The World Health Organization (WHO) recommends vaccinating those who are at high risk of the disease, such as children who live in areas where it is common.

Thimerosal was first introduced in vaccines by Eli Lilly in the 1930s. The vaccine is prepared from cell-culture-grown, chemically-inactivated rabies virus. All of our Merial vaccines are shipped in single-dose vials, which do not contain Thimerosal. The first rabies vaccine was introduced in 1885, and was followed by an improved version in 1908. She also breeds award winning Labrador Retrievers under the Fallriver prefix. Thimerosal is an organomercurial compound and derivative of thiosalicyclic acid with antibacterial and antifungal properties [L1672]. [25] Approximately 90% of all reported rabies cases in the US are from wildlife. [26] Oral rabies vaccination (ORV) programs have been used in many countries in an effort to control the spread of rabies and limit the risk of human contact with the rabies virus. The development of the vaccine resulted in the elimination of rabies in many parts of the Visayas and Mindanao Islands. [6] Most rabies vaccines do not contain thimerosal. [25], There is an oral vaccination in pellet form which can be left out for wild animals to produce a herd immunity effect. Thimerosal is a very inflammatory neurotoxin and genetic mutator and Pittman Moore Animal Pharmaceutical Company warned against its safety “even in dog serum” to Eli Lilly Company in 1935. Rabies is almost always fatal once symptoms appear, but treatment before this is very effective. It has been used as a preservative in vaccines since the 1930s because it is very effective in preventing bacterial contamination. Thimerosal contains ethylmercury, which is cleared from the human body more quickly than methylmercury, and is therefore less likely to cause any harm.

Question: Are there any methods to stop the potential side effects of vaccine reactions? Thimerosal prevents the growth of bacteria in vaccines. [6] Vaccines made from nerve tissue are used in a few countries, mainly in Asia and Latin America, but are less effective and have greater side effects. These concerns are based on the similarities between the symptoms of mercury poisoning and autism. Merial rounds out its rabies vaccine line with the launch of IMRAB1 TF, a one-year, thimerosal-free (TF) vaccine for dogs and cats. [6] It is recommended that those who are at high risk of exposure be vaccinated before potential exposure. Your veterinarian is your best resource for information about the vaccinations that are important to the health of your dog or cat. Answer: The rabies vaccine should be thimerosal (mercury) – free – i.e. [6] After exposure to rabies there is no contraindication to its use, since the untreated virus is always fatal. given a 3-year licensed canine rabies vaccine that also contained thimerosal (mercury) as a preservative [7]. All the doses were obtained by attenuation, but later ones were progressively more virulent. Request PDF | Evaluation of Thimerosal on the Potency and Stability of Inactivated Animal Rabies Vaccine | Abstract Thimerosal is used as a preservative in Rabies vaccine. If you are vaccinating your dog for rabies, make sure you see the label of the vaccine and that the vaccine is thimerosal free. The inactivated virus is formulated with a highly purified adjuvant and is packaged in liquid form. A few companies are making canine rabies vaccines that do not contain thimerosal. [6] It is on the World Health Organization's List of Essential Medicines. The difference between the two vaccines is that one is labled for 1 year protection and the other is for 3 years. Thimerosal In Rabies Vaccines. [6][9], For individuals who have been potentially exposed to the virus, four doses over two weeks are recommended, as well as an injection of rabies immunoglobulin with the first dose. Thimerosal, which consists of approximately 50% mercury by weight, has been one of the most widely used preservatives in vaccines. [11] Because the rabies virus has a relatively long incubation period, post-exposure vaccinations are typically highly effective. DEFENSOR ® VACCINES CONTAIN INACTIVATED RABIES VIRUS FROM AN ESTABLISHED CELL LINE TO EFFECTIVELY HELP PROTECT DOGS, CATS AND FERRETS FROM RABIES Defensor 3 is for vaccination of healthy dogs, cats, ferrets, cattle and sheep 3 months of age or older as an aid in preventing rabies. The letters TF in the vaccine name indicate that the vaccine is free of thimerosal. This study aimed at comparing potency and stability of inactivated animal rabies vaccine with and without thimerosal. Imrab 3 has been approved for ferrets and, in some areas, pet skunks. There are a number of rabies vaccines available that are both safe and effective. Rabies virus strain Pasteur RIV per dose. © 2021 Dogs Naturally Magazine Inc. IMRAB3 TF is a thimerosal-free rabies vaccine, but I believe it is present in most others. The first injection was derived from the spinal cord of an inoculated rabbit which had died of rabies 15 days earlier. Sign up for the Dogs Naturally Newsletter and get over 200 FREE Health Plans and Guides in 2020. A vaccine containing 0.01% thimerosal as a preservative contains 50 micrograms of thimerosal per 0.5 mL dose or approximately 25 micrograms of mercury per 0.5 mL dose. was started in 1967. Initial at 12 weeks, and annually thereafter. The development of safe and effective rabies virus vaccines applied in attractive baits resulted in the first field trials in Switzerland in 1978 to immunize red foxes.
