I know the vets are overwhelmed these days, I rescue and honestly however you get your shots is perfectly fine at this point. There is actually several vaccine and medicine shortages as people take higher priority and well they both need vials, needles, sterilization, and the same manufacturing plants and those resources have been re-allocated.
I hope you find a new vet just understand it is super weird times, so the next vet may not be any different. We have to do enough volume to "reserve" our slots so we can still even get in on a regular basis. Several vets were completely shut down during COVID which just put more burden on those that were open and has just made everything so much harder...lots of people didn't take their pet last year so now its a mad rush to catch up.
