you linked.. but did you listen.. im guessing not.
1:25-1:40
they start using the bodies resources to replicate
at first they fly under the radar.
but when certain numbers are reached they change their behaviour and start damaging the body
...
(which triggers the immune response)
this is where the novel pathogens is explained
the body has no memory B cells yet/alredy to strike early/fast on a new 'under the radar' pathogen
stage..
do you get it yet
watch the whole video where it says it takes 5 days to make and break helper cells. and then more days for the memory B
..
meaning first occurrence/interaction with a certain strain can affect you for a week+
its only then you may have memory B cells to sort out future battles sooner and faster (at the under radar stage)
..
the memory B cells. for say sars 2002 are not releasing the correct shape form antibodies to cling onto the spikes of covid before damage..
this is why. they talk about the incubation period of 5 days and then symptoms. because your body just is not reacting to covid for 5 days+
even super healthy full immune efficient healthy people take over a week to make the memory b cells for covid.
so stop thinking you covid immortal within 24 hours.
..
once you have recovered. you body then has immunity to covid. and you will notice the next infection is handled sooner and faster. you may even get new symptoms like a runny nose whereby your body has recognised the infection early and put antibodies in your mucus to clear out your nose and throat early
but it wont happen on a first occurance of a new pathogen
