They want people to believe they are better than nature!
Any time something is pushed so hard by any entity that just wants to use one sided information that something should be questioned highly.
Natural immunity weaker? Ineffective? Isn't the vacine's mechanics modeled after the actual virus's? Being as the vaccine will have appliances deleted and modified as well as incomplete the effectiveness can be questionable. They have already admitted to failures in the planned operation of the spike proteins being locked onto the cell producing them.
Here's a thought, any living thing, tha vaccine in this case, can find a way to evolve. The mRNA introduced to a host system has the possibility to mutate. Put that in your pipe and smoke it.
Here's another thought, mutations in infectious biolgical agents come about from encountering resistance from hosts immune system or introduces antibiotics. That's how we get "superbugs". Maybe the Delta variant is a result of the vaccine. Maybe the Delta variant is a result of natural immunity. No thought has been mentioned in respect to that scenario.
Now, from the aspect of the 'ol conspiracy theory poit of view..... This virus has been programmed in a lab to act in the manner it does. The people that want to push the vaccine are the same people that had this virus modified. Either it's a money thing, control experiment or an attempt to reduce the populaation (Agenda 21). Why else would they try to get 100% of the population vaxxed? Why else would they deny the efficacy of natural immunity? There's more than than is being presented here than they're letting on.
