>Companies are very interested in unexpected events, particularly bad ones (called “adverse events” in the jargon). Viagra was “discovered” because of an unanticipated side effect of a drug being tested for a heart disorder.
Tell that to Moderna and Pfizer. They, nor the FDA, have shown any interest in adverse events reported by both patients and doctors to VAERS [1], unless whatever hypothetical minimum number of people report it. I've had, as well as Dr. Greg Poland [2], a pretty severe adverse reaction to the mRNA vaccines but our problems remain unaddressed because not enough people have reported it, science knows little about our reaction, or it doesn't monetarily benefit anyone (liability or profit). As for the Viagra discovery, it was a monetary benefit.
Scientists and researchers in the medical field need to realize everyone is different and we have different reactions to various drugs. I guarantee you that carbamazepine was causing my apnea problems. It also caused two other adverse reactions that are not listed as side effects.
Now that I think about it, your entire comment screams pharmaceutical marketing to me.
