You don't have to be Einstein to be aware that the human immune system knows more about viruses than any modern doctors, and it is 100% effective in healthy people.
just saying 'don't have to be einstein' followed by blab. does not make the blab true
1. the immune system knows alot about pre-existing pathogen it had come into contact with before
2. the immune system can and does over react and under react even in healthy people
3. the immune system is only called in when cells send a signal that they have been attacked.
4.the immune system is not smart. on first signal of a new pathogen all they know is to try. they dont yet know how. they have to learn
4. your definition of healthy is not the common definition most people know
5. about ~80% of peoples immune system does not know how to fight a pathogen with a certain spike identifier. the only way to learn is to get infected. there are 2 options:
a. get the replicating virus that kills cells in the lungs - dangerous
b. get a vaccine in the arm that doesnt replicate - safer
6. yes healthier younger people can respond to signals faster. and produce more antibodies faster, meaning they can fight the pathogen faster. but a healthy 70yo is not as quick or productive as a less than healthy 10yo
and a healthy 94yo is even less productive and quick
7.imagine it this way. immunocells trained to fight old pathogens are like 10year vetaren marines. able to go on mission attack old pathogens quick and many squads of them.
but a new pathogen. well thats fresh recruits that have not even gone through 'hell week' they have alot to learn about new battle strategy. it takes longer to recruit new troops and train them
