Gencon,
Given the recent information about those individuals that have had COVID and recovered (https://www.medpagetoday.com/infectiousdisease/covid19/92836), why are you not allowing a positive antibody test to serve as grounds for a bracelet?
There are many medical professionals suggesting to those that have recovered to not get the vaccine due to potential medical implications (see article above), until after they are no longer testing positive for antibodies. And that in many cases the natural immune response is as effective as a vaccine.

"These findings suggest that induced SARS-CoV-2 immunity, whether induced through natural infection or vaccination, is very efficacious against infection (>90%)..."
If a person can show proof of infection, recovery, and antibodies can you reconsider the position on providing bracelets?
