The Scottish Parliament has voted to make vaccine passports mandatory at nightclubs, concerts and other large events.
The nation's model is expected to provide the blueprint for an English certification system.
Negative testing will not be accepted in lieu of a vaccine passport, prompting criticism from some Scottish politicians and health officials who say the passport alone won't prove whether people are passing the virus on, but will adversely affect businesses.
However, Scotland has removed a rule that performers within one metre of each other must wear face masks or use protective screens.
First reported in ArtsProfessional, the restriction provoked alarm among theatres and Creative Scotland.
The Scottish Government changed the rule "in response to concerns about the performing arts sector’s ability to resume work".
New guidance says the exemption will only apply when there is a partition or distance of at least one metre between performers and the audience.
"Because of the continuing risk of transmitting the virus indoors, these exemptions from wearing face coverings without one-metre distancing or partitioning should be the exception rather than the norm."
