Sažetak
We construct certain new extensions of vertex operator algebras by its simple module. We show that extensions of certain affine vertex operator algebras at admissible half- integer levels have the structure of simple vertex operator algebras. We also discuss some methods for determination of simple current modules for affine vertex algebras
