>If you just do a basic per-capita analysis the reduced risk of death is in the range 5-16x I am not questioning that, but couldn't that 5-16x be contributed to the latest strains being far less deadly that the first few strains, much better and accessible treatments (monoclonal antibodies), safer hospital practices (not putting people on ventilators so quickly/easily), etc.? How can we be so sure that the majority of that 5-16x was from vaccination?
