$PULM The corona virus has been engineered to attach to receptors in the lungs (found most plentifully in the lungs of Chinese males). If a drug or vaccine is under development to in some way interfere with this attachment mechanism the preferred route of administration for such a drug would seem to be via inhalation. Of course a delivery vehicle would be needed to attach the drug to. So any big pharma working on such a drug or vaccine would be likely to be thinking in terms of a potential partnership with Pulmatrix. At this time, the announcement of such a partnership could have quite a dramatic effect. That's speculation but it's certainly possible - even likely.
