This pilot project introduced an outreach mobile influenza vaccination program led by a large hospital network in Australia that was designed to target high‐risk and vulnerable populations in a high‐income setting. After identifying key populations, the project engaged stakeholders with established access to these populations. A mobile, nurse‐led immunisation service visited 16 sites where these populations attend and offered influenza vaccine. A total of 520 influenza vaccines were administered. Two-thirds (61%) of those vaccinated had previously received the influenza vaccine, but only around one-third (39%) had received it within the last year. Almost half (45%) of the participants self‐reported a risk factor for severe disease.
