Another reason demand may be slowing is that most people who want it have already had it. People can only handle so many doses at a time (usually 2). At this point, most of the people who used to answer "I want it ASAP" have already had it, and no longer fall into that category.

But yeah, people are hearing about the deaths now, too. Most aren't, because of censorship, but I think it's having at least some impact on numbers.
