Cold- not treatable at present. If a drug company wanted to invest 1bn + in developing an antiviral they could, but getting people to shell out for an expensive treatment for a self limiting minor inconvenience would be a toughie
Flu- this is a potentially deadly disease for which effective treatment would be highly desirable. There are antiviral treatments, they do work, but not well enough to justify widespread usage outside of specific clinical situations
Not sure what you mean by ‘susceptible to both antibodies’
Prescribing is complex, doctors know they don’t work for colds and flu, but people get bacterial complications of flu, and bacterial infections can mimic flu; you can get sued for getting it wrong and failing to prescribe, so sometimes doctors err on the defensive side when they prescribe
