Description détaillée
Background:
The 2019 discovered new coronavirus, SARS-CoV-2, is an enveloped positive strand single strand RNA virus. The number of SARS-CoV-2 infected people has increased rapidly and WHO has warned that the pandemic spread of Covid-19 is imminent and would have disastrous outcomes. Covid-19 could pose a serious threat to human health and the global economy. There is no vaccine available or clinically approved antiviral therapy as yet. This study aims to evaluate the safety and immune reactivity of a genetically modified aAPC universal vaccine to treat and prevent Covid-19.
Objective:
Primary study objectives: Injection of Covid-19/aAPC vaccine to volunteers to evaluate the safety.
Secondary study objectives: To evaluate the anti- Covid-19 reactivity of the Covid-19/aAPC vaccine.
Design:
- Based on the genomic sequence of the new coronavirus SARS-CoV-2, select conserved and critical structural and protease protein domains to engineer lentiviral minigenes to express SARS-CoV-2 antigens.
- The Covid-19/aAPC vaccine is prepared by applying lentivirus modification including immune modulatory genes and the viral minigenes, to the artificial antigen presenting cells (aAPCs). The Covid-19/aAPCs are then inactivated for proliferation and extensively safety tested.
- The subjects receive a total of 5x10^ 6 cells each time by subcutaneous injection at 0, 14 and 28 days. The subjects are followed-up with peripheral blood tests at 0, 14, 21, 28 and 60 days until the end of the test.
