There needs to be a law that public health official's can be sued if there is evidence they conspired to remove information about people's health in a public health emergency.
That information needs to include not just treatment options,but also information on status of any new medicines or treatments they could be prescribed.
Natural methods to improve your own health need to be freely explored and the public health officers,your own doctors and any hospital you might be admitted to.
If that information is kept from you if you ask for it you need to be able to sue these people for damages.
And last but not least rule changes by large organizations like the WHO on what the definition of a pandemic is should be openly discussed and if they are not,the member states should have the option to sue to remove the current leader.
That's just solutions off the top of my head,I have no idea how you would or could make any of that legal,but you own your own body.
