Mate, you work as an MP and a minister *full time*.
You're writing in reply talking about people who are fully debilitated. Permanently disabled and unable to work. Be very careful about comparing your experience to theirs, and making it sound like their experience is yours.
So 8 months ago there were 100 long covid centres that offered talking therapy and damaging physical therapy for conditions that were neurological and biochemical. 100 long covid centres that were *mostly harmful*.
I am just a bird on the internet, but I have a growing suspicion that flu and rsv infections do trigger the immune system in a way that *can* *help* *temporarily* *reduce* susceptibility to Covid.
By temporary I mean like a couple of weeks.
And I put 'can', 'help', 'temporarily', and 'reduce' all in asterisks to emphasise them because this isn't a "flu makes you immune to covid" scenario.
