That isn’t ignoring the science, the science says vaccinate everyone as quickly as possible.

Production continues and continues to increase so there will be more than enough doses to give the second dose as well.

What data we have shows that even with one dose both are well above 50% efficacy at three weeks.

That percentage increases with time even without the second dose as the body goes through the entire transcription and replication phases of antigen specific antibodies and production of the gamma globulins and other immuno globulins (non specific antibodies) has already been ramped up by the first dose as well.

Even if it takes a few extra weeks to get a second dose to everyone this is the most logical route to take.
