Since no one wants the Johnson and Johnson shot now, does that mean there would be no wait for it if I went to a pharmacy that has it?

Right now you cannot get one. 

And you're asking this question in the "Higher Education (University +) section...why again?

No one is offering it right now.  There is a pause in administration of that vaccine while they investigate. 

At this moment, the Johnson and Johnson vaccine is not offered anywhere in the US. Either the FDA or J&J is researching and testing to learn more about the possible risk of blood clots as a side effect. While that us being looked into, the FDA "paused" their approval for emergency use of the experimental drug as a vaccine.

Edit: I do think that if the FDA goes back to allowing that vaccine to be used, many people are still going to want it. Plenty of people just want to be vaccinated against Covid, and aren't that picky about which brand of vaccine.
