Depending on the virulence of the influenza virus strain, as well as the immunological status of the infected individual, the severity of the respiratory disease may range from sub-clinical or mild symptoms to severe pneumonia that can sometimes lead to death. Vaccines remain the primary public health measure in reducing the influenza burden. Though the first influenza vaccine preparation was licensed more than 60 years ago, current research efforts seek to develop novel vaccination strategies with improved immunogenicity, effectiveness, and breadth of protection. Animal models of influenza have been essential in facilitating studies aimed at understanding viral factors that affect pathogenesis and contribute to disease or transmission. Among others, mice, ferrets, pigs, and nonhuman primates have been used to study influenza virus infection in vivo, as well as to do pre-clinical testing of novel vaccine approaches. Here we discuss and compare the unique advantages and limitations of each model.<\/jats:p>","DOI":"10.3390\/pathogens3040845","type":"journal-article","created":{"date-parts":[[2014,10,21]],"date-time":"2014-10-21T10:07:45Z","timestamp":1413886065000},"page":"845-874","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":102,"title":["Animal Models for Influenza Viruses: Implications for Universal Vaccine Development"],"prefix":"10.3390","volume":"3","author":[{"given":"Irina","family":"Margine","sequence":"first","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA"},{"name":"The Graduate School of Biomedical Sciences, Icahn School of Medicine at Mount Sinai,  New York, NY 10029, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4121-776X","authenticated-orcid":false,"given":"Florian","family":"Krammer","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2014,10,21]]},"reference":[{"key":"ref_1","unstructured":"Shaw, M.L., and Palese, P.
