I work in the department of medicine. I used to work in biochem as a research assistant. We do trials worldwide in many things.
Your mileage may depend on where you are and when things become available.
You should consult your MD about vaccine schedules and availability.
Our shots are the ones you get at the med center, since we're part of that. Other areas have lower risk factors, due to lower risk factors. Some of us work in labs, some in the hospital, some in research trials in Africa. Herd immunity means you don't skip people, since that provides a pathway.
Define "approved". You're not in the category that others are in. When BC rolled out shots recently anyone associated with major hospitals was given immunizations. Same here.
Again - there are nasal spray versions of all of these. They may not be the first available or you may be in a low risk group so they are not used in your group. Vectors and pathways are critical in making such decisions. People who travel and are exposed to people who travel, who work on or with people who do medical or biochemical (all part of the same large building structure, we all go to each others seminars) research, or are associated with endemic risk factors are always in the prime group.
Such things may or may not be commercially available to you at the location you are at or in the category you are in. Some may be first wave shots or mists used to get sufficient large scale trials operational. It's not my job to do the protocols for that.
