The Victorian government will bring the COVID-19 directly to homeless and disadvantaged communities through mobile clinics.

People experiencing homelessness and disadvantage will be able to get vaccinated against COVID-19 at pop-up clinics across Melbourne.

Health Minister Martin Foley on Thursday announced community health organisation CoHealth has begun mobile pop-up clinics in the city centre, Collingwood and Footscray.

Each vaccination team includes two community health nurses, a social worker and a worker who has experienced homelessness and will have the capacity to immunise 40 people a day.

The mobile clinics will also visit homelessness services, drop-in centres, crisis accommodation facilities and rooming houses across the inner north, inner west and city in the coming weeks.

"We know that people without a secure home are highly vulnerable to COVID-19, so we are removing any barriers they may have in accessing the vaccine to ensure they can get vaccinated quickly," Mr Foley said in a statement.

Meanwhile, Pfizer eligibility has been expanded at the state-run vaccination centres.

All healthcare workers, hotel quarantine and international border workers and residential aged and disability care workers and residents are now eligible for Pfizer, regardless of their age.

Household contacts of hotel quarantine and border works aged over 16 are also eligible.

More than 1.4 million doses of vaccine have been administered at state-run hubs to date, including more than 500,000 doses in the past month.
