Scottish children could be among the first in Europe to be vaccinated against swine flu.
The mass immunisation plan is expected to begin “within weeks”.
At the weekend, a 26-year-old swine flu patient became the fifth person in Scotland to die after contracting the virus.
He died at Glasgow’s Victoria Infirmary on Saturday.
Health Secretary Nicola Sturgeon is expected to confirm that children under 16, pregnant women, people with underlying health problems and NHS staff will get the first of the 11million vaccines ordered.
It is understood those getting the vaccine will have two doses three weeks apart.
Children could get it on their return to school from the October break, while younger children will be offered it at their local surgery.
The Scottish Government would not confirm its programme for administering the vaccine when it arrives.
A spokeswoman said: “The Department of Health has a contract to supply vaccines on behalf of the UK Government with two companies, Baxter and GSK.
“The manufacturers have told us that we can expect the first supplies of the Baxter vaccine in August and the first supplies of the GSK vaccine later in September.
“This schedule is led by the manufacturers and is therefore subject to change.”
She added: “We are preparing rigorously to ensure that the NHS is ready whenever the H1N1 vaccine arrives, but this does not necessarily mean that vaccination will commence immediately.
“The start point for the programme will need to take account of the procurement process for the vaccine, the licensing position and scientific advice about safety.
“We will not use a vaccine unless we are confident in its safety.”
Saturday’s swine flu death came days after officials revealed a drop in the number of people contracting the virus in Scotland.
Estimates suggested about 3,000 people contracted the H1N1 virus last week, which was down from more than 4,000 the previous week.
The 26-year-old had “significant underlying health problems”, the Scottish Government said.
The man contracted the virus on August 3 and was admitted three days later.
Ms Sturgeon said the death was “tragic", adding “I extend my sincere condolences to the patient’s family.”
