IgE stays on these mast cells for months, even after serum IgE levels have waned. These IgE antibodies have a high affinity for receptors on mast cells in the skin and nearby mucous membranes of the intestinal tract and the respiratory tract. Patients with atopy (dogs, horses) respond to nontarget antigens by making not only IgG but also IgE antibodies. The presence of the nontarget antigens in multiple viral vaccines means that each time a patient receives a vaccine containing the nontarget antigens those same nontarget antigens are available to restimulate the immune response. However, in the population of patients with atopy (those that readily make IgE responses and are often allergic) elicitation of an IgE response by these nontarget antigens presents a potential problem. Even if a small amount of IgG is made against fetal bovine serum proteins, it is usually harmless. For most patients, this is not a problem. The process of vaccine production varies with the manufacturer and the type of adjuvant used, but in general it is impossible for the viral antigens to be completely purified so that the tissue culture products are completely eliminated from the final product. In addition, stabilizers, such as gelatin, can occasionally become a target of an unwanted immune response. When virus is grown in eggs, some of the egg protein can become a nontarget antigen. The actual virus that is the target immunogen is rarely the source of the misdirected immune response. Proteins shed from the cells used to grow the virus are another source of antigen. If the virus is grown on mammalian cells, the most common nontarget antigens are bovine serum proteins, because of the use of fetal bovine serum in cell growth medium. These are proteins that are present in the cell culture medium used to grow the virus to be used in the vaccine preparation. We encourage you to reach out to us large and small animal patients administration of a viral vaccine, particularly an inactivated and adjuvanted viral vaccine, can elicit an IgE response to proteins present in the vaccine that are nontarget antigens. Our veterinarians will answer any concerns you have about side effects. Some possible side effects are loss of appetite, vomiting, diarrhea and swelling at the injection site. Not to worry though as these side effects only last up to 48 hours. Yes, it is possible for some pets to experience some mild side effects. Will my pet experience any side effects after they are vaccinated? Rabies vaccinations are effective for three years, Bordetella is effective for 6-12 months and DHPP, leptospirosis, Lyme disease and canine influenza are effective for one year. Booster shots are necessary because each vaccine lasts for a certain amount of time. The first round of vaccinations should be carried out every three weeks until your puppy is 4 months old.Īdult dogs should receive booster shots once they have completed their last round of puppy injections. We begin puppy vaccinations between 6 and 8 weeks old. Our veterinarians will create a vaccination schedule for your furry pal. When should my puppy or dog be vaccinated? We are here to assist you in protecting your pets and deciding which non-core vaccines may benefit them. Say, for instance, you live in an area that is riddled with ticks our veterinarians would recommend your pet be vaccinated against Lyme disease. Non-core vaccinations include leptospirosis, rattlesnake, Lyme and influenza. Depending on your pet’s lifestyle and environment, they may be exposed to certain parasites and diseases if not vaccinated. Non-core vaccines even though they are not mandatory may also benefit your loyal companion. Does my pet need other vaccines even if they aren’t required by law? Rabies, distemper/parvovirus (DHPP), and Bordetella are the three compulsory vaccines for your puppies and dogs. Core vaccines are also required because of the possibility for transmission between other animals is high. These are mandatory because of the severity of the disease your pet may develop without them. Vaccines required by law are called core vaccines. Contact Us Which vaccines are required by law?
