Would his taking the Antiviral Regimen now help prevent a recurrence of symptoms of asthma if there is still a residual viral presence?

We do not want to be put in the position of making a future prediction here, but in general, given the presence of so many illnesses and others scourges, preventive measures are certainly prudent and viruses constitute a quite large category of menacing organisms in your environment. That is why we have recommended that your followers embrace taking the Antiviral Regimen, given that circulating viruses can continue to be a risk. It is also the case that when people have previously been infected it will make them more vulnerable to a reinfection through the workings of karma if nothing else. While we endeavor to, in effect, clean house and scrub people up in doing the comprehensive healing protocols on their behalf, there will be a historical precedent and it will favor a reoccurrence of the problem compared to someone with no such history.
