More than 11,000 people in Scotland have signed up for Covid-19 vaccine clinical trials.
Volunteers have been described as “a major part” in efforts to find an effective vaccine.
Over 100,000 people have signed up across the United Kingdom but more are wanted.
Researchers have urged more people to sign up, particularly those over the age of 65, and those from black, Asian and minority ethnic (BAME) backgrounds.
UK Government minister for Scotland Iain Stewart said: “I am delighted that more than 11,200 people in Scotland have registered to take part in clinical studies through the NHS Covid-19 vaccine research registry so far.
“Volunteers are a major part in the race to find a working vaccine.
“I encourage people from all groups, particularly the over 65s, frontline workers and those from BAME communities to sign-up as we look to find a vaccine for coronavirus.”
Business secretary Alok Sharma added: “From John O’Groats to Land’s End, everyone has played their part in tackling coronavirus – from wearing face coverings to following social distancing guidance.
“Scientists and researchers are working day and night to find a vaccine that meets the UK’s rigorous regulatory and safety standards, but they need hundreds of thousands of people of all backgrounds and ages to sign up for studies to speed up this vital research.
“I urge everyone to play our part in the fight against coronavirus and join the 100,000 people who have already registered, so we can help save and protect millions of lives.”
