The US is unlikely to reach herd immunity anytime soon, as vaccine demand is dropping with well less than half the population immunized. The unimmunized are a threat not just to themselves, but to the general public, since no vaccine is perfect and reservoirs of infection spawn dangerous mutants. Some public health advocates suggest mandates. I agree. Who should be mandated?
1)Health care and elder care workers.
2)First responders and the military.
3)School children and teachers.
4)I think that it also makes sense for retail establishments to hire only the immunized and advertise fully immunized status.
I think that positive incentives for getting vaccinated should also be encouraged. $100 per vaccination would be appropriate and might make a difference.
