Eligibility requires proof, but state and local officials have yet to establish what documents will be needed, or a straightforward way to sort phony documents from real ones.

At vaccine sites staffers have routinely encountered people using forged documents to try to get shots.

L.A. County Public Health Director Barbara Ferrer said earlier this month that “hundreds” who are not eligible try to get inoculations every day.

“Some of those folks have gone to great lengths to, in fact, establish eligibility when they’re taking appointments from people” who qualify first, Ferrer said.
