Spring booster jabs will be offered to Scots at highest risk of covid from tomorrow.
The latest stage of the vaccination programme in Scotland includes all people aged 75 and over and care home residents.
Letters are also being sent out to parents and guardians inviting children aged five to 11 for their first vaccination appointments. Children in this age group with specific medical conditions have already been invited.
Health secretary Humza Yousaf said: "We know that those in high-priority groups are at higher risk of serious illness from COVID-19, and I therefore welcome the start of the rollout which will offer a further dose to these people.
"Vaccination has been our most effective tool against coronavirus.
"However, the degree of protection offered wanes over time, which is why booster vaccination is needed to maintain the best protection against COVID-19 for those at highest risk of severe effects of the virus.
"The additional booster dose will improve your level of protection significantly and is the best way to protect your health and those around you.
“I continue to encourage everyone to receive the doses they are eligible for as and when they become available.”
It comes as covid infection levels are rising in Scotland, figures suggest.
About one in 19 people in Scotland had Covid in the week ending February 26, according to figures from the Office for National Statistics based on swabs from randomly selected households.
By contrast, infection levels have continued to fall in England and Northern Ireland.
About one in 30 people in England are estimated to have had Covid in the week ending February 26.
