The Mayo clinic will be sued for billions once the evidence of the death clot shot is entered into record in a court of law.
Mayo clinic in jacksonville also won injunctive relief against a family insisting on ivermectin. There is no likelihood based on current survey of rulings and legal rulings that would suggest you are correct — there is currently (i am not saying it is right) immunity for the makers of vaccination against statutory damages. It will not be entered into a court of law in the foreseeable future. Also, it is unlikely that Mayo would not defend this lawsuit which would likely lead to precedent devastating to your position of advocacy.
