Gillian Mackay of the Scottish Greens sets out the reasons behind her party's backing of vaccine passports after "hoping" it would not be a necessary measure.
She says Scotland is "on the brink" of reimposing restrictions and cites health boards that have stopped certain procedures due to Covid pressure.
Ms Mackay asks Mr Swinney to divulge if there has been any more uptake of the vaccination among young people since last week and argues for more encouragement for these age groups to get jagged.
She says the passport scheme does not appear to have increased vaccine hesitancy, but says she "implores" health boards to reach out to groups that have already expressed concerns.
