No, some people who get a repeat infection are getting a worse one. This is not the most common pattern and is why I clarified with "mostly."

What pandemic lasted 10 years at this level? Spanish flu, a bit over two. Russian flu, which was likely a coronavirus (same symptoms as COVID) lasted the same 2 to 3 years. Unless you count "pandemics" such as smallpox and HIV...which lasted a lot longer.

And no, if you look at figures from *everywhere* with a decent number of vaccinations, the deaths and hospitalizations are overwhelmingly in unvaccinated people. Vaccinated people are getting sick from Delta, but not that sick.

The vaccines are working...and saying they aren't just encourages the idiots who won't get them and then end up in the hospital. The Delta variant does NOT evade the vaccines to a significant degree.

We may well need boosters because of variant shifting, but probably not forever, and possibly only in vulnerable groups.

We can't lockdown forever. Humanity isn't made that way. We've already seen that people can't and won't tolerate it.
