Given that a vaccine may not provide total protection, they should consider how to sell a potential early, safe but only moderately effective vaccination. For instance, calling it a "COVID-19 Immune Booster Shot," and be very transparent that it reduces your protection against the virus but is not total immunity. Then the world won't lose faith in science and medicine when folks who had the shot are testing positive and even dying.

Hopefully either way the amount of news coverage will be enough that most people will get informed about it, in a way that they don't for most issues.
