More than 500 people in Dorset are to test the safety and effectiveness of a new coronavirus vaccine.
The study in Bournemouth is looking for people in the county from the most 'at risk' Covid-19 groups to take part.
This includes those with stable, pre-existing health conditions, those over 65-years-old and those from Black or Asian ethnic backgrounds.
The testing will look at how the vaccine protects against the virus across a wide range of people.
Scientists said because of this, they also need people aged 18-84 to take part in the study, in order to "help us make sure that any vaccine developed will work for everyone".
The volunteers will either be given the vaccine or a placebo injection, so researchers can confirm the participants' immune response.
Dr Patrick Moore, a Dorset GP said: "This important research will help us to find a safe and effective vaccine for COVID-19, to protect us all more quickly and end the pandemic sooner."
People interested in participating in the study are being encouraged to sign up to the NHS COVID-19 Vaccine Research Registry.
