Recombinant lentivirus can be produced at a moderately high titer and is efficient in target cell . Pneumonia. Most data suggest that the immune response to coronavirus is transient (<6 months).4 With regard to COVID-19, the more severe the clinical complications, the greater the immune response against SAR-CoV-2, as is the case for most viral infections. The main signs are a cough, a fever of 100.5 or higher, and general malaise. They break down the proteins, including .
