Dengue Tetravalent Vaccine Containing a Common 30 Nucleotide Deletion in the 3'-UTR of Dengue Types 1, 2, 3, and 4

The invention relates to a dengue virus tetravalent vaccine containing a common 30-nucleotide deletion (delta30) in the 3'-untranslated region (UTR) of the genome of dengue virus serotypes 1, 2, 3, and 4. The previously identified delta30 attenuating mutation, created in dengue virus type 4 (DEN4) by the removal of 30 nucleotides from the 3'-UTR, is also capable of attenuating a wild-type strain of dengue virus type 1 (DEN1).

HIV-1 Infection Detection Assay for Seroconverted HIV-1 Vaccine Recipients

Available for licensing and commercial distribution is a serological test specifically designed to distinguish between antibodies generated in HIV vaccine recipients and those generated in a natural HIV infection. The method is useful in HIV vaccine development and clinical studies as it can readily detect early breakthrough infections in seroconverted vaccine recipients, thus providing the information required to determine vaccine efficacy. The test kit includes diagnostic peptide fragments derived from human immunodeficiency virus-1 (HIV-1).
