Paid or not paid, I don't understand why we need to do contact tracing at this stage?
Plus, given that some americans can tell you to fuck off by a simple request to put on a mask, can you imagine contact tracers telling them to quarantine? They'll probably shoot them.
It'd suck if you get shot on the job as an unpaid intern. Even with pay, not sure the job would be worth it. Just focus on making more vaccines please!
