A vaccination programme will support those experiencing rough sleeping and people staying in homeless hostels or night shelters, protecting a group at high risk of serious respiratory illness who are too often left behind.
Secretary of State for Health and Social Care, James Murray said: "For too long, people experiencing homelessness have faced some of the worst health outcomes in the country and have too often been missed by services many of us take for granted.
"They should not miss out on potentially life-saving protection against flu when they can be at similar, or even greater, risk from the disease than some groups already eligible for vaccination
"This change is about putting that right. By rolling out flu vaccinations to homeless people, we are delivering on our promise to tackle health inequalities and make sure support reaches those who need it most."
The update comes after the government accepted the expert advice from the Joint Committee on Vaccination and Immunisation to make NHS pneumococcal and seasonal flu vaccinations available to those experiencing homelessness.
