To be fair, not all approved medical treatments are ever subjected to a properly designed trial. There are many medical treatments and practices which have never been through a randomised trial - but they are accepted through long periods of clinical observation.
A pandemic on the other hand, requires rapid decision making in the Executive arm of Government without the benefit of scientific scrutiny - and properly so.
However, the difference between a medical treatment and a public health mandate where both are not underpinned by scientific evidence is that medical treatment is voluntary but public mandates are often imposed with enforcement power of the State.
When a health policy/mandate is enforceable by the State, it is my opinion that such policies by subjected to scientific analysis during the implementation period to see if they can be backed up by proper scientific evidence.
In my view, there has been 2 years to properly study the various facets of Covid public health policy. There have been various observational analysis - some even at a population level, but nothing robust has ever been carried out - especially in the area of masking, social distancing, lockdowns. It is sad though because there is always going to be another pandemic of an airborne virus, and I fear we have lost a precious opportunity to fully test all the health decisions. We head into the next airborne virus pandemic without rigorous scientific data on the best way to conduct public policy
The best I can tell is that N95 is the best mask to use. Mask use indoors make sense especially around medically vulnerable people. But at the moment, I can’t say that an enforceable masking mandate has the backing of rigorous scientific analysis.
The reason that people still don’t agree on masking and debates rage on in forums like this, is because there is no convincing scientific data one way or another. And maybe even with proper scientific analysis there is no convincing data - if so, should the enforcement power of the State be used in that circumstance?
And I write this wearing an N95 and have been since 7am this morning
