Steve Clarke has revealed "over 75 per cent" of his Scotland squad are vaccinated against or recovered from Covid-19.
The manager is confident his players now have a good level of protection against the virus after suffering some costly disruption throughout the pandemic.
Clarke has lost the likes of John McGinn, John Fleck and Billy Gilmour to isolation requirements at various points, as well as new coach Austin MacPhee during the last international break.
He echoed Liverpool manager Jurgen Klopp, who earlier this week expressed his frustration with Premier League players not getting the jab, in stressing the vaccine's importance.
"Obviously we want as many people to be vaccinated as possible," Clarke told Sky Sports.
"I'm of a certain age where it's a no brainer to get it done. You have to understand some younger people might think it's not the thing to do.
"But this current squad, I think there's over 75 per cent or are double-vaccinated.
"We're pretty well covered within the squad now.
"And, obviously, the more people who get double-vaccinated the better it is and the safer it is for everyone in the country.
"My message is - get your vaccinations, please."
