Someone shows up at your medical facility presenting COVID symptoms, and they test positive for it.
How do you know if this person is vaccinated or not?
We ask, and in our semi-rural area most of the vaxxes were given within our system and are charted.
Occasionally we have unknowns.
Last week the critical (ICU) census was 13, 11 unvaccinated, 1 vaccinated, 1 unknown.
The state is 56% vaccinated.

Tests 160236 and 164068 look for antibodies that your immune system produced in response to the presence of the SARS-2-CoV virus itself.
Set those aside, and look among the other tests that are not nasal swab tests . . . and find tests that look for the spikes.
