Bluetooth devices have unique addresses. They should broadcast their device name along with the address. If they don't have an associated name, some devices won't display them in a list when you scan for nearby bluetooth signals. I dont' know much about iPhones. With Android, you can, with developer mode, allow them to be displayed.
I have personally tried to scan areas to see if there is validity to the "covid shots are causing people to emit bluetooth signals". I don't have a strong opinion either way, but I haven't dismissed the idea, yet. I live semi remotely, and I get a clean scan at home. When at work or in various locations, I get lots of unknown devices. When I happen to think about it, I discretely check this and haven't been convinced yet that a signal is directly tied to a person, but I will test more to see if I can confirm this for myself.
The theory aside, I'd bed that the app in question is simply substituting the word "Vaccinated" for any unknown bluetooth address, or it's simply an edited photo. If OP really installed a random apk from some random source, that isn't the wisest thing to do. I have a few open source apps that I guess aren't any more trust worthy that I've installed, so I can't really throw stones. But also, even "trusted" apps from "trusted" repositories like "the Play Store" are just as likely to have back doors ... ... ...
Hey, so to your point of clean signal at home but at work it goes crazy. Here are a list of things that potentially could be there:
Smart watch.
Smartphone.
PCs/macs.
Computer mice (if they have bluetooth).
Pretty much any modern enough device that has Bluetooth has the capability to send and receive Bluetooth Low Energy signals. Because as in the name, low energy usage is a huge thing, especially for mobile devices.
