An Interview with MilliporeSigma

摘要

Viral vaccines contain either inactivated or attenuated viruses with the aim of inducing a protective immune response in the recipients against the respective infectious disease. The induction of this immune memory is made up of two parts; antibodies which bind to an invading virus and prevent proliferation and also the cellular immune memory which has multiple pathways to prevent and eliminate viral infection. Such vaccines are available against a variety of viral diseases, including mumps, measles, rubella, and influenza. The Oxford/AstraZeneca vaccine against COVID-19 is of a slightly different type of viral vaccine, containing a weakened and modified adenovirus originally isolated from chimpanzees, this virus has been genetically modified to express the spike gene from the SARS-CoV-2 virus.
