> I forgot where I saw it, but the news said that something like only 30% of people (in the US) got vaccinated.

This is almost certainly 'fully vaccinated'. The number of vaccinated americans is closer to 80% https://usafacts.org/visualizations/covid-vaccine-tracker-states/ .

> As for the second point, most people I've heard who got covid describe it as similar to a flu

The people who got HIV said the same thing.

At first.

And permanent heart damage later. See above thread.

> This whole thing about damaging multiple organs and passing the blood brain barrier is all true of the vaccine, not necessarily covid itself.

Yes covid itself. And sure, that probably happens too with the vaccine, to a lesser extent. The spike proteins alone, though they definitely do bad things to wherever in the body they manage to be, don't do as much as the virus itself. At least in the case of the vax, the dose is controlled.

> covid is very similar to a flu in how it travels through the body.

It's more similar to Dengue fever and HIV.
