A method for limiting exposure to infectious disease by controlling access to a controlled access venue to admit individuals who have tested non-infectious for a particular highly infectious disease or have received a vaccination against the same comprises receiving, at a central website operator server, consumer user identification information from consumer users and storing that information in a consumer user database associated with the server. A biometric identifier from the consumer users is transmitted to the consumer user database and each associated with its respective associated consumer user to form an enrollment record. Identity of a presented individual is collected at a medical certification point and an authority record is created in an accessible authority database. At said medical certification point, an antibody test or vaccination is administered and the same is noted in the authority record. A biometric is collected from a venue presented consumer at a presentation venue, compared to authority records for a match, and the result provided to the venue.
