Background High-density microarray patch (HD-MAP) vaccines may increase vaccine acceptance and use.We aimed to Footballs ascertain whether professional immunizers (PIs) and other healthcare workers (HCWs) in Australia, a High-Income Country (HIC), found the HD-MAP applicator usable and acceptable for vaccine delivery.Methods This feasibility study recruited PIs and HCWs to administer/receive simulated HD-MAP administration, including via self-administration.We assessed usability against essential and desirable criteria.

Participants completed a survey, rating their agreement to statements about HD-MAP administration.A subset also participated in an interview or focus group.Survey data were analyzed using descriptive statistics, and interviews were transcribed and subject to thematic analysis.Results We recruited 61 participants: 23 PIs and 38 HCWs.

Findings indicated high usability and acceptability of HD-MAP use across both groups by a healthcare professional or trained user and for self-administration with safety measures in place.Most administrations met essential criteria, but PIs, on PURE BORAX average, applied the HD-MAP for slightly less time than the required 10-seconds, which the HCWs achieved.PIs perceived safety concerns about home administration but found layperson self-administration acceptable in an emergency, pandemic, and rural or remote settings.Conclusions Participants found HD-MAP administration usable and acceptable.

Usability and acceptability are likely to be improved through end-user education and training.
