12 de ene. de 2021 · Live-attenuated vaccine. A live-attenuated vaccine uses a living but weakened version of the virus or one that’s very similar. The measles, mumps and rubella (MMR) vaccine and the chickenpox and shingles vaccine are examples of this type of vaccine. This approach uses similar technology to the inactivated vaccine and can be manufactured at scale.
9 de sept. de 2021 · To generate a candidate for a SARS-CoV-2 live attenuated vaccine, we isolated temperature-sensitive (TS) mutants from a Japanese clinical isolate, which could replicate at low temperatures (32 °C or 34 °C) but showed impaired proliferation at 37 °C .
