LOL ... I wish you are right, but as a famous aussie once said ...

I have already heard that, and am asking one question. (Sorry if this is naive, I'm no virology expert!)

If the above happened to be true, how could a vaccine for it ever work?

If I add up all the information I have read so far I think there are a couple things to be aware off:
1) The flu symptoms caused bij Covid-19 are not that bad.

Yeah. Well, according to some that have had it, it's no picnic either. No idea the percentage of people for whom it's light or bad, and if this % is similar to seasonal flu.

--- End quote ---

According to many reliable reports, the majority of people that get it will get it have no symptoms, or symptoms mild enough not to even seriously suspect they have it (i.e. so that's likely less serious symptoms than the flu)
If it's not the majority then it certainly seems to be a very high percentage.

Well, that is a big issue. The only reports that we have come from complete testing of "closed" populations. These are situations where everybody in a sample was tested. For example, everyone on a cruise ship or in a nursing home.

Look at the table in this article https://www.cebm.net/covid-19/covid-19-what-proportion-are-asymptomatic/ that reviews those situations. The proportions are all over the place. I believe that most are valid, but none of the numbers can be generalized to populations with much confidence.

Many folks, including myself, are in favor of some degree of random testing (both for evidence of infection and immunity as well as a self reporting of symptoms) in countries to specifically address the issue because it is integral to a response strategy.

I just saw this today and it is the first time I see comorbidity numbers, reducing the number of deaths by ~40%.

https://www.cdc.gov/nchs/nvss/vsrr/covid19/index.htm?fbclid=IwAR1xKt19EwyxwqGeRRMiaXCXdyyIBJ1FmLS6-m24EJapcW_JUrI8AtwwraQ

Given the text mentions the number of deaths may increase due to delays in reporting (it says one to eight weeks), how is the current 60k death toll really being counted?

This whole thing is terribly confusing and, with such data deviations, there is no right answer if one option is better than the other due to the criticality/lethality of this disease.

No. What doesn't kill you makes you stronger; IOW: if you stay in a sterile environment your immune system doesn't get any training. Most vaccines work by training your immune system to a weaker variant of a virus so it is ready for when the real deal hits.

They are already doing that in several countries by testing donated blood for Covid-19 virus anti-bodies. This gives a statistically relevent sample (which can be split by ages groups). From the last numbers I've seen the percentage of people in the Netherlands and Belgium that have had the Covid-19 virus is about 4% on average.
