Scotland's chief medical officer Dr Gregor Smith said it is "wonderful news" that the Medicines and Healthcare products Regulatory Agency (MHRA) has approved the Covid-19 vaccine from Pfizer and BioNTech.
Speaking at the Scottish Government's daily Covid announcement, Dr Smith said: "When I become eligible for receiving my vaccine dose, I will be there with my sleeve rolled up to make sure I get it."
But he added the Scottish Government is not currently advising those who are pregnant to get the vaccine because of "limited data" about its use in this group.
Nicola Sturgeon also welcomed the UK becoming the first country in the world to approve the Covid-19 vaccine from Pfizer and BioNTech, saying it may mark the "beginning of the end of the pandemic".
She also warned delivering the vaccine to more than four million adults across Scotland will be a "massive, massive operation".
The Scottish Government is working with health boards, councils and the Army on its vaccine plans, with the First Minister saying these are already "well developed".
Ms Sturgeon said: "This is the biggest logistical peacetime challenge that the country will ever have undertaken.
"The planning is well under way. But there are people in this organisation right now who are full-time working on this to make sure this goes as we need it to."
The jab has been shown in studies to be 95% effective and works in all age groups.
Earlier Dr Gregor Smith said on Twitter that it is just the first of several vaccines in the pipeline, and its approval "begins to change everything for our future".
National clinical director Professor Jason Leitch tweeted that "science, collaboration and logistics has got us to this day".
He added: "It's a very important moment. There will be months of roll out until normality but it's a crucial step. Thanks to all."
