I am not too familiar with inoculating bunnies as we don’t need to do so in the states, but I have done my fair share of horses at home! Things to consider when having vaccines done “over the counter” so to speak:

Is it a clean, fresh needle?
Has the vaccine been kept at the appropriate temperature since its purchase?
Where are these vaccines coming from? (for horses I was able to get everything but rabies from my local feed store!)
What is the expiration date on the vaccine?
Is your bunny getting the full vaccine, or is the breeder splitting them? (this is an unfortunately common practice)

And this is meant as no offense but: who is saying the breeder is responsible? Not to say he/she isn’t, but if the recommendations are coming from your local pet store or other breeders they might be rather biased.

Of course I am one of the few that is all for doing immunizations at home. I grew up helping my mom do them and started doing them myself when I got older so for me it is just something I consider normal. Not everyone is comfortable with this, and for those I do recommend you go with someone you trust. You might also look into contacting a local rabbit rescue and seeing if they offer a low cost vaccine clinic.

My big concern is whether your rabbit is healthy enough for a vaccine. The reason dogs and cats go into vet clinics for vaccines is because, if there is an under-lying health problem, then getting a vaccine could potentially make the animal very sick or even cause death. Where I live legally all dogs and cats need to have a health check by a veterinarian before getting any vaccine. I live in Canada, so we don’t have any rabbit vaccines either, so I’m not very familiar with protocol, etc. But what I see here is breeders doing at home vaccines on dogs and cats and even though they have gotten a health check done, they aren’t following the proper protocol and vaccinating too close together causing their animals to get the same viruses that they are vaccinating against. I’m not trying to change your mind, but I just want you to make sure you are doing the safest thing for your rabbit.

I would look up any possible health complications tied to the vaccine, there can be allergic reactions etc. Has your bunny had the vaccine before? I know some people do it with their dogs, horses, etc but most of them have discussed it pretty thoroughly to know all the details of it with a vet in the past that I know. We don’t have the vaccines here, so not familiar with the risks involved with that particular one.

Could you also call a vet and get their advice? Vets know that we can’t always get in, and they know people purchase and vaccinate themselves. Perhaps a vet or the rescue would be willing to give you precautions and advice when going this route?

Ktykitten had some great advice. I’d ensure you are there for the vaccination, check the vial(expiry and for previous punctures), check where she keeps it, and see her put the needle on the syringe both from a new or autoclaved package. Also some vaccines need to be mixed, so she would put a needle on the syringe, draw it up and then shoot it into another vial. She should then replace the needle before drawing up the mixed vaccine and injecting it. This is because the needle dulls and will make the injection slightly more painful if she doesn’t replace it.

I think you could ensure all is well without raising any backs, by feigning intense interest in the process (ohhh is that how you do that? So is that a new needle? Now what are you doing? Oh thanks, I really think this is neat etc) -that might make it more comfortable for you to question the process.
