Subsidy Framework for Vaccines on the National Adult Immunisation Framework (NAIS)

The National Adult Immunisation Schedule (NAIS) provides guidance on vaccinations that persons aged 18 years and older should receive to protect themselves against vaccine-preventable diseases.

Certain adult groups are more susceptible to, or at risk of, acquiring vaccine preventable diseases if they have not previously received the vaccination and are in contact with individuals who have the infection.

Vaccines recommended under the NAIS helps reduce risk of infections among susceptible individuals and related complications, morbidity and mortality.

The current subsidy framework for vaccines on the National Adult Immunisation Framework (NAIS) is as shown below.
