>You and your family should jump to the front line and help build this immunity

Yes by allowing people to go outside, work and do their normal activity. It builds their and other people immune system. Prolong lockdown will cause immune system to go down.

We are on HN, not on a forum on healthy diet and recipe with this "bolster immune system" nonsense (that i accept reading on those forums). If something seems logical and simple, it just means you have to do your own research.

Either you are immunodepressed or you are not. Well, actually you can have an hyperactive immune system, that's what Dr house call a lupus, or a cykotine storm.

Really fast and with no details : You can boost your protective response going out and interacting with other people/kids but this will not boost your immune system. I understand this is an easy confusion as the protective response is caused by the immune system but i assure you, this is not the same thing.
