I was under the impression they no longer wanted to know the vaccination status of new Covid cases. This way they can’t report “breakthrough” cases. Once that data is lost, there is no way to retrieve it reliably.
They only test the vaccinated if the have Covid symptoms. The unvaccinated get tested as soon as they are admitted for any reason, even if no symptoms, and are sent to Covid ward if positive. The automatically become unvaccinated Covid hospitalizations and deaths (if they die of whatever had them got to the hospital).
