Top 5 Personal Worst Pathogen Sick

[The Magic Pudding.]

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.

Hmm

"What is the difference between being vaccinated and being immunized?


Vaccination: The act of introducing a vaccine into the body to produce protection from a specific disease. Immunization: A process by which a person becomes protected against a disease through vaccination. This term is often used interchangeably with vaccination or inoculation."

I'd had a vaccination, a few more since. 
I suppose I was only partially immunised, depending on your preferred definition.
