Inactivated virus formulated vaccines such as Hepatitis A and smallpox proved to be reliable approaches for immunization for prolonged periods. In this study, a gamma-irradiated inactivated virus vaccine does not require an extra purification process, unlike the chemically inactivated vaccines. Hence, the novelty of our vaccine candidate (OZG-38.61.3) is that it is a non-adjuvant added, gamma-irradiated, and intradermally applied inactive viral vaccine. Efficiency and safety dose (either 10(13) or 10(14) viral RNA copy per dose) of OZG-38.61.3 was initially determined in BALB/c mice. This was followed by testing the immunogenicity and protective efficacy of the vaccine. Human ACE2-encoding transgenic mice were immunized and then infected with the SARS-CoV-2 virus for the challenge test. This study shows that vaccinated mice have lowered SARS-CoV-2 viral RNA copy numbers both in oropharyngeal specimens and in the histological analysis of the lung tissues along with humoral and cellular immune responses, including the neutralizing antibodies similar to those shown in BALB/c mice without substantial toxicity. Subsequently, plans are being made for the commencement of Phase 1 clinical trial of the OZG-38.61.3 vaccine for the COVID-19 pandemic.</subfield> </datafield> <datafield tag="650" ind1="1" ind2="7"> <subfield code="2">opendefinition.org</subfield> <subfield code="a">cc-by</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Tastan, Cihan</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Kancagi, Derya Dilek</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Yurtsever, Bulut</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Karakus, Gozde Sir</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Mehmet Ali Aydinlar Univ, Anim Applicat & Res Ctr, Istanbul, Turkey</subfield> <subfield code="a">Ozer, Samed</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Abanuz, Selen</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Cakirsoy, Didem</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Mehmet Ali Aydinlar Univ, Vocat Sch Hlth Serv, Istanbul, Turkey</subfield> <subfield code="a">Tumentemur, Gamze</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Yeditepe Univ, Genet & Bioengn Dept, Istanbul, Turkey</subfield> <subfield code="a">Demir, Sevda</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Seyis, Utku</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Kuzay, Recai</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Elek, Muhammer</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Kocaoglu, Miyase Ezgi</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Mehmet Ali Aydinlar Univ, Vocat Sch Hlth Serv, Istanbul, Turkey</subfield> <subfield code="a">Ertop, Gurcan</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Mehmet Ali Aydinlar Univ, Histol & Embryol Dept, Istanbul, Turkey</subfield> <subfield code="a">Arbak, Serap</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Mehmet Ali Aydinlar Univ, Histol & Embryol Dept, Istanbul, Turkey</subfield> <subfield code="a">Elmas, Merve Acikel</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Labcell Cellular Therapy Lab, Istanbul, Turkey</subfield> <subfield code="a">Hemsinlioglu, Cansu</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Acibadem Mehmet Ali Aydinlar Univ, Med Biol Dept, Istanbul, Turkey</subfield> <subfield code="a">Ng, Ozden Hatirnaz</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Akyoney, Sezer</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Akyoney, Sezer</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="b">article</subfield> <subfield code="a">publication</subfield> </datafield> <datafield tag="542" ind1=" " ind2=" "> <subfield code="l">open</subfield> </datafield> <datafield tag="100" ind1=" " ind2=" "> <subfield code="a">Turan, Raife Dilek</subfield> </datafield> <datafield tag="260" ind1=" " ind2=" "> <subfield code="c">2021-01-01</subfield> </datafield> <controlfield tag="005">20221007103713.0</controlfield> <datafield tag="909" ind1="C" ind2="O"> <subfield code="o">oai:aperta.ulakbim.gov.tr:239638</subfield> <subfield code="p">user-tubitak-destekli-proje-yayinlari</subfield> </datafield> <datafield tag="856" ind1="4" ind2=" "> <subfield code="z">md5:28102a1d4231a4036174830bad6356e2</subfield> <subfield code="s">417</subfield> <subfield code="u">https://aperta.ulakbim.gov.trrecord/239638/files/bib-6adbe137-fe57-43c4-a38c-d32b733ff8ad.txt</subfield> </datafield> <datafield tag="540" ind1=" " ind2=" "> <subfield code="u">http://www.opendefinition.org/licenses/cc-by</subfield> <subfield code="a">Creative Commons Attribution</subfield> </datafield> <datafield tag="024" ind1=" " ind2=" "> <subfield code="a">10.1038/s41598-021-95086-4</subfield> <subfield code="2">doi</subfield> </datafield> </record>
