Do different regulations apply for vaccinated or recovering persons at events?

According to the Federal Infection Control Act, vaccinated and recovered (hence, immunized) persons are considered at least equal to those who have tested negative for Covid. In cases where a negative Covid test certificate is required, it suffices that immunized persons present proof of immunization (i.e. of full vaccination or a Covid infection that was determined at least 28 days but not more than six months prior to the event). Additionally, in cases when access is restricted to people holding 2G status, immunized persons may be granted access, persons who have tested negative for Covid not.
