Vaccination death

Our baby, Tinker Bell was a six year old, almost 7 pound Chichawa. We took her in for her yearly vaccinations last week. Less than fifteen minutes later, she was dead. She had never experienced any problems with her shots before. Our vet said she had never seen a death as a result of the vaccinations, but she knew it was a risk. We didn't realize the risk involved. Thank you for your web site.

EC: We are so sorry for your loss.

I had my Shiba Inu, 12 years old, vaccinated with about his 10th lyme vaccination in June. About 48 hours later he began being lame on his right rear leg. The vet would not hear us out on it being due to the vaccination, but could not find any other reasons for the lameness. He has now progressed to not being able to walk on either hind leg. He "shuffles." Today at the vet the vet again could find nothing wrong and sent us on our way. They were quite offended that I think it could or might have something to do with the vaccine. They actually told me I could just get a copy of my dog's file and go elsewhere. I have gotten the copy. How rude of them, this dog has been there for 12 years and I had other pets there for over 25 years. I was given an antiinflammatory and sent on my way.

We have had a maltese dog for many years. She is about 12 and recently had her yearly vaccinations (the first 5 types they normally give). About an hour after having them she threw up and was very lethargic for the rest of the day. Normally she is a very attentive dog but she became listless. Thankfully the side effects only lasted a day or two.

Her sister had also been vaccinated but had been given the new three yearly vaccination and a nasal delivered vaccination and did not display any side effects.

On 8/15/09 my male neutered cat was vaccinated with FVRCP and FeLV. Within a few days he developed a hard lump at the injection site.

On 10/12/09 he was injected with the 2nd dose of these two vaccines, he was listless for the remainder of that day, but resumed normal activities on 10/13 and 10/14. But on 10/15 he was in very bad shape, completely inactive and refused to eat or drink. On 10/16 he continued to lay in one place and would not eat or drink. I took him to the vet on 10/17 at which time he was placed in intensive care for 2 1/2 days. The vet is not certain that he reacted to the vaccine or some other source of infectio, and suggested that we may not vaccinate him next year.

Previously I had a Scottish Terrier that developed cancer around the age of 10 years, and passed away at 11 years. The vet mentioned that annual vaccines may be contributing to the occurance of cancer in animals.

My 4 1/2 month old french bull do had her DHLP/P-C3 vaccination. The next day she walked a little funny-her hind end seemed to over wiggle. Within a week she has only partial use of her back legs with the left being the worse. The vet has no idea or at least has not returned calls regarding any information they may have found. Bottom line she still is eating drinking, peeing and pooping like a regular puppy. She is bright and alert but her walking abilities are worsening. What shall I do? Is this normal or can this be from the vaccination? Will she recover and what can I do?

I lost a kitten today. He appeared to be completely healthy and then received his 3 way distemper, Calici, Rhinitracheitis vaccine- stopped eating- started gagging up any food I put in his mouth, had labored breathing, and died. Within 3 days. Beautiful soon to be show cat- an Ocicat. I had modified what vaccines they get as I lost one last year also. Even had a necropsy done and it showed a healthy cat- whose organs shut down after his vaccine.

I read an article online saying it is common for this to happen as we inject 3 live viruses at once into a tiny body and they have to be able to fight them of. The article said the killed vaccine is more harmful and suggested the 3 components be broken down into single vaccines.

As for people- they can do all of the skewed studies they want- but we know our autistic son had vaccine issues. The flu vaccine was especially devasttating for him- to the place where we had to stop it.

I know they are a necessary eveil- but very scarey to me.

Vaccination Side Effects

We had a Golden Retriever who ended up with kidney and liver disease after she was vaccinated and died a year later. We gave her all the recommended puppy shots but did not have her regularly vaccinated because we didn't believe it was necessary. When she was 6 we brought her in and had her vaccinated for Rabies, Lymes & distemper. A month later we brought her in to have a lump removed and they tested her blood and found the problems. She was so sick we had to put her down less than a year later. She was perfectly healthy before those immunizations and I am convinced that is what killed her.

First I am sorry to hear of your loss. However, everyone likes to think their dog is healthy before something goes wrong. Did they biopsy the lump or get a diagnosis on what it was? A 6 year old golden retriever could have numerous problems that you don't know unless previously checked. The kidney problems obviously were asymptomatic and you still would have never known without the blood work until it was too late. It could have been there even before it was vaccinated. So it would be a BIG assumption to claim the cause was the vaccinations. We all understand that vaccinations can cause reactions, but it is a rarity and isn't enough reason not to get annual vaccinations. Without vaccinations, imagine the havoc infectious diseases would play in our pets lives.

vaccination reaction

Our dog was impounded and given a rabies and dhpp-bdin, without our consent. Since then he has lost weight and continuing too, diarrhea and vomiting (this has stopped) and is now refusing food. We don't have the money to take him to a vet.

Reaction to Lyme Disease Vaccination

My three year old Pomeranian received a Lyme vaccine on April 4, 2009. I lost her three weeks ago; she was only 3-1/2. On the night she received the vaccine, she began to flop to the side and couldn't find her food dish - it was the saddest thing I'd ever seen. She couldn't control herself, she would walk in circles. We took her to a neurologist the following Monday and the final diagnosis was enchephylitis/menengitis. There was necrosis in her brain like something had triggered an autoimmune reaction. Although, no one will say or admit that the Lyme vaccine may have been the cause due to an allergic reaction, I really have to wonder! We knew this was a terminal illness, but what triggered it? We were able to keep her for only five months following, but she was constantly on meds to fight back the autoimmune disease. I will definitely not allow the Lyme vaccine to be given to her sister who is still healthy and providing much joy in my life. This was such a devastating experience for us and her sister.

My 4 year old cat was vaccinated yesterday and has become very ill. He received his rabies and leukemia shots and within 2 hours was unable to walk straight, almost as if he were intoxicated. His eyes were dilated funny and looked as if they were only half open. He lost control of his bowels on the floor and has been sleeping continuously. He has never exhibited any of these behaviors before and I am certain they are caused by the vaccinations. He seems to have great discomfort when I move him and he cries like he is miserable. I hate this! I'm going to search for other solutions to remedy these side effects and find an alternative to vaccinations for my pets. Putting my sweet cat through this seems very inhumane!

My dog last year was due for his 3 year shot and because I was a month and 1/2 late the vet said you will have to come back in a year on time and get it again. So I did like she said to days after the rabies shot he got bloody lumps around his eyes and lumps and discoloration on his nose. It won't go away they gave him steroids but when he goes off of them it returns. They said we think he has isomatic demiphaphy. One doc at petsmart banif White says it probably from the shot the other Elliot is say we dont' know that and wanted me to take a 300 dollar test, and writes on the paper I denied the test. They know darn well it's just what they said. I'm angry. I took in a beautiful healthy, expensive, my baby Italian Greyhound who now will have to see the vet every month and it will be costly for me, and he doesn't feel good. I want to know who's responsible. The rabies shot was a pfizer. I want their phone number to let them know. I want to know if I can file a case against them and make them pay my dogs bills.

My cat Pinot, 1.5. years old, had his immunizations yesterday and has been tired, lethargic and sore for 24 hours. I am quite surprised and disturbed by this as the vet never mentioned any weird side effects like this. Pinot had 3 shots: Rabies (3 yr), FVRCP, and Leukemia. I am not sure if the reaction was because he had all 3 at once or what. Any feedback is appreciated.

It is not uncommon for animals, like humans, to have a slight inflammatory reaction to vaccines. This can cause low-grade fevers, decreased appetite, and lethargy. Your vet SHOULD always warn you of these side effects. My cat had a reaction like this a couple years ago after she recieved her FVRCP and rabies vaccine. Since that time my husband and I have done a lot of vaccine related research. We have come to learn that although most vets will not tell you so, you should in fact NEVER give more than 1 vaccine at a time-especially to small animals. Many vets will do multiple vaccines at once because it is easier, and insures that the animal will receive the vaccines they are due for since not all pet owners are responsible enough to come back multiple times just for a shot. However, my belief is that it is worth it to make an extra trip or 2 (each at least 2 weeks apart from one another) to decrease my pets risk of having vaccine related reactions.

We have a Golden Retriever puppy, 11 weeks old. The breeder told us that when he received his 1st puppy shot, he had a "possible" reaction one day later. The pup was lethargic and wouldn't get up or walk. He was taken to the vet who was not sure what was wrong but put the pup on steroid medication. When we got him, he was a happy, healthy puppy with no problems that we could see. We told our vet and gave her the records from the breeder's vet. When it was time for our pup's 2nd shot ( DAPP-CV), we "pre-medicated him with Benadryl. He was fine until the 2nd day after the vaccination when he vomited, became lethargic and just very sick. The vet kept him and gave him IV hydration and medication for 2 days. We took him home today. He is alert and eating, but is unable to use his back legs and yelps when he is picked up. He is incontinent of urine and stool. So far we have spent $575 which wouldn't bother me at all if he was well now....he isn't. I can only pray he recovers. I will NOT let this beautiful pup have any more vaccines... EVER!!
