This one of those ‘must explain’ scenario’s, which when left unaddressed, erodes the credibility of authorities…
You have no claim to science, if you cannot explain even a basic observation.
Mongolia is a fantastic experiment.
They clearly got Covaxid-21 and not Covid-19. But I am not qualified to cite the mechanism involved, only the observation of the effect.
Ignoring this however, will build mistrust in the population. It will be your fault, not theirs.
I am not qualified to name the mechanism either, but we know Covax suppresses the immune system. ABN
