Here's a study with a sample comparing 596,618 vaccinated matched with the same number of unvaccinated people by my own healthcare provider:

This healthcare provider is able to follow up on people with detail for a really long time - they are notified of any vaccination, PCR test result, hospitalization and death within the country. They've likely made it possible to calculate the same data for the current day within a moment's notice, and use this information for quick decision-making.

I would expect other healthcare providers in other countries to have pooled this information if they are able to do so (and possibly publish it too).

Its unfortunate that they exclude prior infection from study. Why not study them as a separate cohort? 36% of Americans have been infected. What percent of the unvaccinated public have a prior infection? It seems like a 100% prior infected control group would be appropriate. Where is that data?
