There's been some high profile criticism of test-negative method for vaccine effectiveness, as well as counter-criticism.
Yet remarkably little in media saying what the method actually does, why it's useful, what the limitations are, and how we can improve it.

Again, this concerns a passenger.

WHO reports no new suspected cases on the ship heading to the Netherlands. They remain in regular contact with the captain, who says no one onboard currently shows symptoms.
