Geert Vanden Bossche, DMV, PhD, does not consider the nature of the COVID-19. It is a very stable genome because it has an unique function that eliminates variations in its replication process. This is extremely important because of the Spike Protein has to be consistent or the virus will not be able to invade the cell to hijack the ribosomes for the translation process which makes new viruses. I cannot describe this mechanism in detail, but the researchers know about it and are confident the vaccines will immunize using the stable Spike Protein as the antegen.
You have no clue what you’re talking about.
And extreme medical exposure with full PPE is a different situation, but all kinds of hospital circumstances (including the population of workers who had been most vulnerable early on) and approaches were changing in early April, 2020.
