Please give me some hope! Vaccination Lump

My 2 year old kitty was vaccinated for rabies with an adjuvanted killed virus. Two weeks after, I discovered a small lump at the vaccination site (rear right leg). I'm aware of the dangers of VAS, but got enough feedback that said it will most likely go down on it's own in time, that we decided to just keep a close watch on it.

Now, here we are one month post-vaccination, and two weeks post-lump discovery, and there has been no change in size. We did see the vet last night and she said that, although it still has a good possibility of going away on it's own, personally she would suggest removing the lump surgically now to just eliminate the risk. Money is not an issue, but we really hesitate to involve anesthesia/surgery unless absolutely necessary. We have a very 'delicate' little guy. We've decided to wait one more week, and if there's no change, we'll choose the surgery (ugh!)

What I want to know is, have any of your kitties ever had a vaccination inflammation/lump that took this long to subside? I'll have more hope if so... The internet is full of worst case scenarios, so I'm worried sick. Help!

Thank you all so much for your replies. Pookie, I too hesitate about the anesthesia because Marvin has epilepsy, and is just a very petite, highstrung little boy.... he developed his seizures disorder immediately following his neuter surgery, which is why I make the connection to anesthesia. He's not had a seizure in a whole year now (thank god!), and we are currently in the process of weaning him off of his phenobarbital. He's had so much to deal with thus far in his short little life, this lump issue is just another wrench in the midst of everything else.

My cats have never had anything but Purevax rabies vaccinations in the past. After extensive research, I decided years ago that I didn't want anything else for them. In this instance, the vet gave him the wrong injection, despite what all his records said. That makes this doubly upsetting... this shouldn't be happening at all. I know that any injection has risk, but personally I see enough connection between adjuvant and site inflammation and cancer to connect the dots.

I DO trust the vet we just took him too, it is not the one that gave him the vaccination. She said the lump is pretty small and mobile, it's up in the skin and not connected to any muscle or other tissue at this point. I think the most important factor here in why she'd like to remove it is the length of time it's persisting. That is my biggest worry too. Every day I get down in front of him, hold him by his little shoulders, and beg him to please make it go away today. ha. aww...if only.

Anyway, thank you all. The examples of lumps that have lasted for 3 weeks or longer before going away DO give me hope that this will go away. Keep 'em coming!

I hope I have a similar experience to yours... it's true, checking every day is maddening, because progress (if any), will probably be very slow. Yesterday I felt that it was smaller, and was happy all day. Today, I feel like it's bigger, and am in a funk again.

Anyway, unless I've totally botched my signature here (which is possible, I'm not very good at the whole image combining/editing thing!), you'll see Marvin below, along with my sweet girls, Lola and Spivey. All my babies!

Just wanted to close out this thread by saying that, after 9 weeks, Marvin's injection site lump is completely GONE. Whew! Today is the first day (and I check it EVERY DAY) that I cannot locate or feel it at all.

Thanks to those of you that shared your similar stories (which kept me from worrying to death). I'm so happy that my baby isn't (at least currently) one of the truly sad VAS statistics.
