This study aimed to design and evaluate a serotype\u2010specific multi\u2010epitope vaccine (MEV\u2010DV4) targeting the conserved capsid protein of DENV4 using integrated reverse vaccinology and immunoinformatics approaches. Conserved, antigenic, non\u2010allergenic, and non\u2010toxic B\u2010cell, cytotoxic T lymphocyte (CTL), and helper T lymphocyte (HTL) epitopes were identified and assembled with a \u03b2\u2010defensin adjuvant and PADRE sequence using optimized linkers. The final construct demonstrated high antigenicity (0.8559), structural stability, favorable physicochemical properties, and excellent solubility. Structural validation confirmed 97.6% of residues in favored Ramachandran regions. Molecular docking revealed strong interactions with TLR4 and TLR8, particularly MEV\u2013TLR8, and molecular dynamics simulations supported the overall stability of the complex. Immune simulations predicted robust humoral and cellular responses with strong memory formation. Experimental validation in an albino mouse model using an alum\u2010adjuvanted MEV\u2010DV4 formulation showed early and potent antibody responses, with peak HI titers at day 21. Notably, antibody titers induced by MEV\u2010DV4 were statistically comparable to those produced by a commercial inactivated dengue vaccine at all tested time points (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&gt;\u20090.05), while no adverse reactions were observed. These computational and experimental findings demonstrate that MEV\u2010DV4 is a safe, immunogenic, and promising serotype\u2010specific vaccine candidate against DENV4. Further neutralization and challenge studies are warranted to advance its preclinical development.\n                  <\/jats:p>","DOI":"10.1111\/1348-0421.70048","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T09:47:12Z","timestamp":1770889632000},"page":"241-258","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Integrated Computational and In Vivo Assessment of a Novel Multi\u2010Epitope Vaccine Against Dengue Virus Serotype 4 Capsid Protein"],"prefix":"10.1111","volume":"70","author":[{"given":"Elham Mohammed","family":"Khatrawi","sequence":"first","affiliation":[{"name":"Department of Basic Medical Sciences Taibah University, College of Medicine Madinah Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0298-1848","authenticated-orcid":false,"given":"Syed Luqman","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Biochemistry Abdul Wali Khan University Mardan Mardan Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rasha","family":"Alonaizan","sequence":"additional","affiliation":[{"name":"Department Zoology College of Science, King Saud University Riyadh Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed Mudasser","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Microbiology Abasyn University Peshawar  Mardan Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad Kashif","family":"Obaid","sequence":"additional","affiliation":[{"name":"Lanzhou Veterinary research Institute Chinese Academy of Agricultural Sciences Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.3402\/iee.v3i0.19839"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph18063197"},{"key":"e_1_2_13_4_1","first-page":"89","volume-title":"Handbook of Zoonoses, Section B","author":"Halstead S.
