I am very skeptical of anything that purports to treat multiple illnesses and this vaccine does sound a bit out there but given the information in the article further research is most definitely warranted and i hope it gets done.
I agree, it does violate the "if it sounds too good to be true" rule, and "extraordinary claims require extraordinary evidence".
I am hopeful maybe something will come from it though.
Like the murmurs with long covid being "helped" or "cured" by covid vaccine. Some of the other claims like ivermectin for treating covid. We need to study it carefully before we make any conclusions. There are people out there taking ivermectin instead of just taking the vaccine.
So harm can come from not following the evidence. Putting aside subjecting someone to a non-efficatious treatment, and all the potential side effects, forgoing treatments known to have some degree of efficacy, you still don't want to give someone false hope.
