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. https://www.biospace.com/article/comparing-covid-19-vaccines-pfizer-biontech-moderna-astrazeneca-oxford-j-and-j-russia-s-sputnik-v/ https://www.biospace.com/article/comparing-covid-19-vaccines... 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. https://coronavirus.jhu.edu/from-our-experts/q-and-a-how-much-does-it-cost-to-get-a-covid-19-test-it-depends https://coronavirus.jhu.edu/from-our-experts/q-and-a-how-muc... https://www.talktomira.com/post/how-much-does-coronavirus-covid-19-testing-cost-with-or-without-insurance https://www.talktomira.com/post/how-much-does-coronavirus-co...
