Have I not repeatedly said it needs to undergo a properly formatted clinical trial to establish efficacy and safe dosage, before mass distribution?
For any authority to approve distribution to a large population before those are understood would be criminal negligence. Especially with a drug that is already known to have sever side-effects.
Once a comprehensive trial has proven it safe and efficacious, if Trump wants to crow that he was right, let him.
In the meantime, what are the safe and correct dosages for:
A child of 5 with Covid-19?
A 75 year old with emphysema or cardio-pulmonary disease?
