We conducted a survey experiment to investigate if mentioning COVID-19 vaccine in messages encouraging seasonal flu vaccination will negatively affect people\u2019s attitudes toward receiving a flu vaccine. The experiment was embedded in a survey fielded in South Dakota in April 2024. Participants were registered voters in the state. We used difference-of-means tests and logistic regression to analyze the data. Results showed no statistically significant differences between the participants in control and treatment groups regarding the likelihood of receiving a flu vaccine (OR: 1.012, CI: 0.594 - 1.724) or their belief in the safety of the flu vaccine (OR: 1.333, CI: 0.707- 2.511). We observed the same patterns when we only looked at Republicans. Attitudes toward flu vaccination were primarily driven by peoples\u2019 current flu vaccination status. We found that mentioning COVID-19 vaccines in flu vaccination messages did not negatively affect people\u2019s attitudes toward flu vaccine. Public health workers and officials might not need to shy away from mentioning COVID-19 vaccines when communicating other vaccines.<\/jats:p>","DOI":"10.1371\/journal.pgph.0005180","type":"journal-article","created":{"date-parts":[[2025,9,10]],"date-time":"2025-09-10T17:31:01Z","timestamp":1757525461000},"page":"e0005180","update-policy":"https:\/\/doi.org\/10.1371\/journal.pgph.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["No negative effect of mentioning COVID-19 vaccine in influenza vaccine encouragements: Evidence from a survey experiment"],"prefix":"10.1371","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1096-325X","authenticated-orcid":true,"given":"Filip","family":"Viskupi\u010d","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6928-4246","authenticated-orcid":true,"given":"David L.","family":"Wiltse","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2025,9,10]]},"reference":[{"key":"pgph.0005180.ref001","unstructured":"Cdc.
