It's not realy moral hazard, it's about what is the goal. If the goal is to slow down the pandemic, then the "irresponsible spreaders" should be vaccinated first. On the other side, if the goal is to punish "irresponsible spreaders", then they should be vaccinated last. But that also means that pandemics would not be slowed down, and the ones taking that decision will be responsible for further spreading.
