Opportunistic influenza vaccination in the home: broadening access in isolated times.

Background: Influenza is a vaccine-preventable infection that causes serious illness. The mandate to prevent an influenza epidemic has increased with the COVID-19 pandemic. However, isolation restrictions have reduced interactions with healthcare professionals. We aimed to determine whether these barriers could be overcome by offering vaccination via an ambulatory setting for the first time.

Methods: During a 12-week period, patients receiving care through the Hospital-in-the-Home programme were offered immunisation during their home visit. Logistical cold chain barriers were addressed, and patient acceptance was measured.

Results: Cooler boxes with temperature loggers were designed to monitor the cold chain. 157 eligible patients were contacted, of whom 96 (61%) consented and received in-home injectable influenza vaccine, with no major adverse events. 52/96 (54%) were first-time influenza vaccine recipients. Most refusals (28/41, 68%) were for immunisation concerns, not home administration.

Conclusion: This pilot shows ambulatory influenza vaccination is feasible, safe and overcomes some barriers.
