TABLE 2.

Major epidemiological features on SARS‐CoV‐2

The vast majority of the global population has already been infected with SARS‐CoV‐2.

Previous infections with SARS‐CoV‐2 significantly protect against reinfections and even more so against severe COVID‐19.

Infection fatality rates have significantly declined over the course of the COVID‐19 pandemic.

For natural, hybrid and vaccine‐induced immunity, the protection against severe COVID‐19 is more sustainable than against SARS‐CoV‐2 infections per se.
