Funding of vaccines for elderly through public assistance has positive effects on prescribing of vaccines for private purchase recipients.

Key Evidence: A publicly funded 23vPPV (23 valent pneumococcal polysaccharide vaccine) program in Victoria, Australia not only dramatically increased vaccination coverage among the elderly in the public purchase program, but in other Australian states and territories that did not have a public program, the number of prescriptions issued for 23vPPV actually increased over the same period.
