Last I heard, the "vaccines" were only tested for preventing symptoms. I think anything beyond that is wishful thinking. Also, preventing symptoms can mean suppressing immune system.
Maybe I should clarify this ("immune system" part). A fever for example is almost always a response by your immune system, it is not directly caused by stuff that attacks your body.
Suppressing this fever will remove a tool in the toolbox of the body, which makes it less efficient in doing its job, which in turn, on makes you more sick. A dangerous thing to do
