It would probably cost less to just administer a proven safe and effective vaccine anyway than it would to test that person even once.

3 shots of Pfizer ~ 60 USD < -- VS -- > 100+ USD ~ Single test to see if someone's infected, surely a test to see if someone is naturally immune at best costs this or more.

Pfizer seems to cost about 20 USD per dose, so even with the three dose regime (2 initial shots plus a later booster) is expected to cost under 100 USD; most of the other shots cost less.

As there is no currently known technology to reliably test if someone is immune I'll grab data for the next closest similarity: a test to see if someone is presently infected. Nearly all of those tests cost in the range of 100 to 200 USD, with some rare outliers above and beneath.
