I think you misread the article, granted it buried the lede. The suspect is an instant hit of multiple (in this case two) infections at the same time, when in normal conditions only one at a time would be likely.

The solution to this issue is both unlocking lockdowns more carefully to detect such problems, and deploying vaccines if such a problem is identified.

If the problem was ending the lockdowns, why don’t we just live in a permanent state of lockdown? With mandatory vaccines? Seems like that would work

Not practical, unfortunately. Plus, in typical conditions, neither of the viruses is highly problematic. Only when you get both at the same time you're more likely to suffer, and when unvaccinated to either.

Kind of the same problem with COVID, it can also contribute to a terrible secondary infection. In this case, quite some time after even recuperating from it.

To add to the thought experiment: If it were possible to isolate every single human being (and animal etc.) a considerable number of pathogens would die out.
