The Individual Immunity Collar is the life insurance of the week: whoever earns it cannot be sentenced. In week 1 it was lifted by Aurélie and Sheila, yes, there may be more than one winner. In week 2, who is shielded?
"Yes" resolves if Javier Márquez wins individual immunity or salvation (the Collar/Tótem de Inmunidad Individual) in week 2, per TV Azteca's official announcement. "No" resolves if they do not. This market is INDEPENDENT: there can be more than one individual-immunity winner in a week (as happened in week 1), so each market in the group resolves separately. If no individual immunity is contested that week, the market is canceled. Trading closes at the start of that week's individual immunity challenge (official date per TV Azteca). Confirmed by TV Azteca's official broadcast.
