Here is the thing I'd say every single time when people say “Science is Settled”. Science is the questioning, is the investigating, is the researching of information. Science is never “Settled” since there is always new information. Sometimes there is agreement among most scientists, but questioning, investigating, and researching IS science. Having differing opinions IS science. Having alternate methods IS science. Science is a never-ending quest for more knowledge, even if you don't like that knowledge. That is why every single vaccine, medication, etc. should be completely and independently tested, and all available data inputted for review. If the data does not support the intent, then that “biochemical” should be denied use.
