I'm afraid that Biden may fall from Covid in a similar way as Ford from H1N1. IMHO, the only way to prevent it is to stop the whole corona or economic crisis fear-mongering, and do some uncertainty management. As a part of it the public should be taught that as much as it's impossible to make predictions for Corona/any virus/any exponential process (unless the margin of error of several magnitues is acceptable), it's pretty easy to predict the number of deaths due to a properly tested vaccine (and it won't be 0). The virus evolution with a purely random component is another kind of uncertainty to be aware of. Y'know, it's a little more complicated than Bachelier thought (?) when he ripped off physicists' maths
Truth is the only way to prevent the situation from turning into an even worse chaos (whatever it means). We don't have enough toilet paper to afford it!
