What are his non tested theories and treatments?
The vaccines themselves are experimental and you’re worried about non tested theories and treatments?
The vaccines are not experimental. They are approved under EUA. The fact that you are denying is that they each went through clinical phased trials 1-3 like anything else. There were over 100,000 doses given in clinical trial.
The fact that is is brought by EUA recognizes an urgency exists that makes it reasonable to utilize the vaccine to contribute to reduction of spread of disease.
The EUA necessarily requires that there are no other safe and efficacious treatments of the disease. While there are other proposed treatments such as ivermectin and HCQ they fail on efficacious which would be something that was strong enough to stop progression or spread of disease. Whatever activity these medications have against covid, despite millions of treatments with the medications it did not significantly reduce or stop the trajectory of the disease in terms of spread or severity to be judged worthy of not pursuing other modalities control covid.
Early on there was great interest in these meds. If it were a cure the pandemic would have ended. It was not. So we need to continue to pursue treatments and vaccines. Vaccines are now clearly making on roads alongside of natural immunity (and yes I agree those who have recovered do not need vaccine) and the emergence of targeted therapeutics specific to covid as antivirals that will be not unlike tamiflu.
This will control the pandemic to minimal impact. But what we cannot say with any truth is that nonspecific therapies offer an acceptable level of treatment to abandon any other treatment or prevention modalities.
