I emailed Sarah Constantin about this question. I didn’t end up hiring her (my parents decided they didn’t want to take supplements—luckily they’re working from home now), but she did say:
BTW, the apparent “contradiction” isn’t really one. Immunostimulants, taken when healthy, reduce the incidence of respiratory tract infections; once you get an infection like COVID-19, the immune response often gets so strong it kills you.
So I think taking immunostimulants on an ongoing basis is a good idea, but you should stop if you think you might be infected with COVID-19.
Update: Apparently some have been interpreting this Twitter thread as an indication that the virus may take advantage of immune system activity to infect you? Which could mean that immunostimulation is bad?
