This is a very good and important point. In a good year, if we can convince 40% of the eligible population to get a flu shot, imagine the challenge to get the >= 60% coverage needed to confer herd immunity. Just having a good, safe vaccine available isn’t enough. We have to convince an unusually large number (compared to influenza) of people to get vaccinated, and I worry about how hard that will be.
Vaccines required by workplaces or schools have higher compliance with the recommendations than The flu vaccine. COVID-19 vaccine could well be legally required at all schools, and potentially even legally required at workplaces as a condition of opening (certainly healthcare and allied fields would likely require it the way they do TB vaccines; the larger the mandatory population, the less compliance you need in the voluntary population to reach any given overall target.)
It's my opinion that the coronavirus vaccine may be different.
Workplaces are going to require people to have the vaccine come back to work if only for liability reasons. I haven't run into workplaces requiring a flu shot and I've worked food service my whole life.
