No, they should not be made at a loss, and I did not suggest they be produced in such a manner.
My point, however, remains they are making these vaccines as part of a for-profit enterprise, and therefore the allegedly lower margins (especially given the higher volume sold) are not a reason to trust the vaccine makers that any vaccine is therefore safe and appropriate for all. Regulatory agencies must do their job and one should consult with a reliable doctor regarding the best course of action/schedule.
