The Chinese one is a "traditional" killed virus type, while the Russian one is based on the Human Adenovirus, which provokes an immune response that is also effective against Coronavirus. When the Russian one was first announced a couple of months back there was a good article about it, and how it was based on a dual mechanism which made it more effective. THe Oxford vaccine is similar, but based on a monkey Adenovirus, introducing an unknown quantity. I try to be non-sectarian and scientific and unprejudiced, though sometimes prejudices are in order. Cheers David.
