I wrote earlier that “recovered individuals have a kind of superpower and would be highly desirable workers.” Antibody tests will soon be able to identify these workers and that will help to reopen the economy because not only can these workers go back to work relatively safely they can also work relatively safely with those who are not immune, thus a kind of multiplier-effect for the workplace. Hence, Italy and the UK are talking about “Immunity Passes” that would allow (we hope) immune workers to go back to work.
One factor, however, which hasn’t been taken into account is that the demand to go back to work may be so strong that some people will want to become deliberately infected. If not done carefully, however, these people will be a threat to others, especially in their asymptomatic phase. Thus, if we use Immunity Passes they will need to be combined with variolation, infecting people with small doses of the virus to create immunity under controlled conditions, as suggested by Robin Hanson.
