Despite the fact that olfactory loss after an influenza vaccination is noted in one case report, no quantitative olfactory testing was performed. Hence, it is unclear whether, in fact, olfactory dysfunction can be associated with such vaccinations. This study was designed to (1) identify patients from the University of Pennsylvania Smell and Taste Center who attributed their empirically determined chemosensory disturbances to influenza vaccinations and (2) determine whether influenza vaccinations add to the degree of olfactory or gustatory dysfunction due to other causes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective analysis of self-reported etiologies of 4554 consecutive patients presenting to the University of Pennsylvania Smell and Taste Center with complaints of chemosensory dysfunction was performed. Those who reported dysfunction secondary to influenza vaccinations were identified. Additionally, in a subset of 925 patients for whom detailed inoculation histories were available, it was determined whether the number of lifetime inoculations added to the deficits due to other causes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Nine of the 4554 patients (0.19%) attributed olfactory disturbances to an influenza vaccination. None complained of taste dysfunction. All nine had abnormally low scores on the University of Pennsylvania Smell Identification Test (p &lt; 0.001), with three being anosmic and six microsmic. Seven had elevated phenyl ethyl alcohol detection thresholds (p &lt; 0.05). Two cases exhibited mild-to-moderate loss of whole mouth taste function. Of the 925 patients, no association was evident between the number of lifetime vaccinations and the chemosensory test scores. In accord with previous studies, age and sex were significantly related to the test scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A very small percentage of the 4554 patients evaluated (0.19%) attributed their chemosensory dysfunction to a prior influenza vaccination. No influences of the number of lifetime influenza vaccinations on the test scores were evident in the subset of 925 patients whose dysfunction was due to other causes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2500\/ajra.2014.28.3987","type":"journal-article","created":{"date-parts":[[2014,1,24]],"date-time":"2014-01-24T19:47:38Z","timestamp":1390592858000},"page":"50-53","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Influenza Vaccinations and Chemosensory Function"],"prefix":"10.1177","volume":"28","author":[{"given":"Richard L.","family":"Doty","sequence":"first","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Austin H.","family":"Berman","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad","family":"Izhar","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugh B.","family":"Hamilton","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danylko","family":"Villano","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Britney E.","family":"Vazquez","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maja N.","family":"Warrum","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariam","family":"Mahbob","sequence":"additional","affiliation":[{"name":"Taste Center, Department of Otorhinolaryngology\u2013Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,1]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-1108-7_11"},{"key":"e_1_3_1_3_2","first-page":"6","volume-title":"Immunization Safety Review: Influenza Vaccines and Neurological Complications.","author":"Stratton K.","year":"2004","unstructured":"StrattonK., AlamarioD.A., WizemannT., and McCormickMC (Eds).
