How is that a reply to my post? You're just using your usual trick of using someone's post as springboard to launch more of your propaganda from.
And the fact is that all vaccines have been through RDBPC. But not all with your ideologically required saline placebo because the world considers that it is unethical to use a saline placebo where an existing vaccine exists. And in terms of the actual testing, an existing vaccine used as a placebo is perfectly suitable as the new/modified vaccine is tested against a vaccine of known performance. I know you don't understand this as you continually demonstrate no knowledge of science or mathematics, or even logic for that matter, but it is fact.
And you will note that in any of the Covid-19 trials I have posted up the placebo is saline. They use saline as there is no existing vaccine and therefore it is ethically appropriate.
