Do you actually believe the number of doses would be an arbitrary decision? The effectiveness has been tested at different intervals after each dose. The manufacturing and logistics change dramatically when there is more than one dose. If one dose was needed the vaccinations could be mostly done in spring instead of through the summer. I can't believe anyone would actually think something so crucial would be chosen arbitrarily or on a whim.
