Top 5 Personal Worst Pathogen Sick

[Bucky Ball]

Having Covid, i'd been immunised.
The first time, coughing and being unable to take a breath for a bit, I thought it likely I was going to die.
I spent a couple of days staying awake, spitting to avoid a fluid build up and triggering near death cough experiences.

If you mean that by having had one strain of Covid, you're immunized, you're wrong. 
There are at least 5 strains circulating, with a new one arising fairly frequently.
