When someone tells you they have a long term health condition, "But that condition isn't a problem any more, because I once read a news article about one study with a new drug" is never a good response. Asthma & the Covid/Budesonide trial is no exception.
Someone who takes medications multiple times every day has probably already read up on treatment options and new developments in more depth than a casually interested observer.
And someone who has spent over a year risk assessing their every move according to their level of clinical vulnerability will have noticed news stories about studies that could alter their assessed level of vulnerability, and they may well have read further around the subject.
E.g. They have read that the trial excluded anyone already taking steroid inhalers. That it reduced symptoms of moderate Covid but it is not a miracle cure. They have read studies that asthmatics taking higher dose ICS, or multiple other medications, are actually at higher risk.
They will know how careful they have been, & realise those more stringent Covid precautions could be a factor in lower than expected mortality figures. They will know that even if Covid doesn't kill them, they don't want to be left with further breathing problems long term.
A clichéd phrase, but one very fitting for the Covid pandemic: "If you're not worried, you haven't been paying attention." Well, being listed as vulnerable for a year made us pay attention!
