The move, prompted by new advice issued by the Joint Committee on Vaccination and Immunization (JCVI) will see tens of thousands of Scots in insecure housing conditions join priority group six.
The same cohort also contains unpaid carers aged 16 to 64, alongside adults with eligible at-risk health conditions.
Ms Freeman said the Scottish Government “fully expected” to offer first doses of the coronavirus vaccine to the remaining priority groups by mid April, with increased supply of the vaccine allowing around 800,000 people to be vaccinated over the next two weeks.
Official figures show that 1,844,636 people have received their first dose of a coronavirus vaccine since the start of the rollout, up 18,836 from yesterday.
A further 149,409 have now also received their second dose.
