Yes, likely. I also would not make sense for a small company to build distribution and marketing channels (marketing might not be necessary in this case). Also, big name. Nobody knows BionTech but the name Pfizer signals trust. In most cases the small company is actually getting bought by big pharma.

I work on a medical consumer device. Would be madness to market this ourself. A big company has the resources for distribution and marketing.
