Patent number: 10888612Abstract: The present invention relates to vaccines of DNA that code for specific viral sequences. The DNA vaccines against yellow fever according to the invention are based on the sequence that codes for the yellow fever virus envelope protein (p/YFE). Besides the wild p/YFE construct, sequence E was also fused with the sequence that codes for the human lysosome-associated membrane protein (h-LAMP), generating the construct (pL/YFE). The results of the invention are considered to be very promising, since both constructs can induce T-cell response against the same epitopes induced by the 17DD vaccine, and the pL/YFE construct can also induce a satisfactory concentration of neutralizing antibodies. The pL/YFE vector was inoculated in mice, before intracerebral challenge with the virus of yellow fever. Surprisingly, 100% of the mice immunized with pL/YFE survived the challenge.Type: GrantFiled: September 28, 2018Date of Patent: January 12, 2021Assignee: The Johns Hopkins UniversityInventors: Ernesto Torres de Azevedo Marques, Rafael Dhalia, Romulo Maciel Filho
