Step-by-step explanation:
In order to cover the cost of providing free flu vaccines to uninsured patients, the hospital should apply for grants or seek funding from public health organizations or government agencies.
Grants are financial awards given by organizations or agencies to support specific projects or initiatives. Hospitals can apply for grants that are specifically intended to promote public health and prevent the spread of diseases like influenza.
By successfully obtaining grants or funding, the hospital will be able to offer free flu vaccines to uninsured patients, thus contributing to the prevention of new cases of influenza.
