Beyond the nasty and sometimes life-threatening symptoms that COVID can bring, there's another risk: long COVID.

It's the collection of prolonged symptoms including brain fog, smell loss and fatigue.

And while we know that being vaccinated drastically reduces your risk of a bad bout of COVID itself, a lingering question has been whether it also protects you from long COVID.

Also on today's show:

* Is there any research work being done to modify the virus to develop a relatively benign but transmissible COVID variant which could be released to "crowd out" the current dangerous variants?

* Is there a chance that Omicron is different enough that instead of replacing Delta, you get both if not together then one after another?

* And we're after your stories about getting third-doses. Was it easy? Or hard?
