EXPRESSION VECTOR AGAINST SEVERE ACUTE RESPIRATORY SYNDROME VIRUS SARS-COV-2

The invention relates to biotechnology, immunology and virology. There is created an expression vector containing the genome of recombinant human adenovirus serotype 26, wherein the E1 and E3 regions are deleted, and the ORF6-Ad26 region is replaced by ORF6-Ad5, with an integrated expression cassette selected from SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3 (variant 1). Therein, the sequence SEQ ID NO: 5 was used as a parental sequence of human adenovirus serotype 26. Further, there is created an expression vector, containing the genome of recombinant simian adenovirus serotype 25, wherein the E1 and E3 regions are deleted, with an integrated expression cassette selected from SEQ ID NO: 4, SEQ ID NO: 2, SEQ ID NO: 3 (variant 2). Therein, the sequence SEQ ID NO: 6 was used as a parental sequence of simian adenovirus serotype 25. Furthermore, there is created an there is created containing the genome of recombinant human adenovirus serotype 5, wherein the E1 and E3 regions are deleted, with an integrated expression cassette selected from SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3 (variant 3). Therein, the sequence SEQ ID NO: 7 was used as a parental sequence of human adenovirus serotype 5. There is also developed a method of utilization of the developed expression vector for creating an immunobiological agent for the induction of specific immunity against severe acute respiratory syndrome virus SARS-CoV-2.
