David said "does not mean...does not stop"; CDC said "don't yet know". 
My "not yet completely clear" is closer to "don't yet know" than to 
"does not mean...does not stop".

In other words, no-one now can say for sure whether immune 
people---either via vaccination or via having been infected---can infect 
others or not.  As long as it is not clear, we should be on the safe 
side, but there are some hints that being immune does at least 
substantially reduce the risk of infecting others.

For what it's worth, I just got back home from a medical appointment, 
where I discussed this topic, among authors; my physician agrees with 
me.  She also said that there is some preliminary evidence that 
vaccination might provide longer-lasting immunity than an infection.
