Experts are starting to hint at the possibility that the virus will mutate like the common flu and recur every year, so immunities will be redundant and vaccines unusable every year forever, this could be our new normal unless we eradicate it on a World scale

Unfortunately we have these reports from Korea that people tested positive again after being declared recovered. Still not clear what went wrong there, this news seems to have fallen off the radar.

There is no need to hint. An english university has done partial gene sequencing on various corona patients. It turns out they can separate people into types A, B, C. Mostly: Type A are people from the USA and China, Type B from Europe, Type C from other areas. Type A is closely related to the bat virus, while types B and C are mutations. Interestingly, people from the Wuhan region are NOT type A, putting into question that the virus actually originated from Wuhan bats.

Even as research is running on highest gears everywhere, the virus still mostly is a mystery.

There are at least 18 different strains already, all still small mutations, enough to track the virus but not to alter its behavior. Here is an animation of how the virus has spread over the world. https://nextstrain.org/ncov/global
It's not hard fact, just one interpretation of the data.

They don’t count recoveries here. In fact I don’t even know where worldometers got the 250 number from, should be zero, or a ‘-‘ like Wikipedia has (or had, didn’t check there in a while). The number of recoveries is much higher than 250 in actuality though, the amount of people in hospitals and ICU have been steadily declining for almost two weeks now, and then there’s the non-hospitalized mild cases. At the moment there’s still about 1100 people in ICU. The death number could be a bit higher, but not by much, here they’ve already been counting deaths outside hospitals so there won’t be a big correction like we saw in France for example. The main statistics agency has pointed out an increase in average weekly deaths compared to other years slightly beyond the counted Coronavirus deaths, that are unaccounted for though.

Yeah, like I explained in the post above, they don’t count recoveries, at all, here so the death/cure ratio is not usable.

When its all said and done, its probably around 1%.
(In the western world, with proper healthcare)

But like others have said, theres now a few differnt strains and many many mutations within each "main" strain.
On Iceland they tested and found over 40+ mutations within a strain they had on the island.

On Faroe Islands, they found 2 differnt main strains (just like the chinese talked about), and found one was barely spreading (ei. you could kiss someone and not easily get it), while another was spread basically just walking by someone else infected breathing.

So how dangerous this virus is, *could* also depend on which version of it you get.

This would suck sooooooooooo much.
I hope next wave, we have enough PPE, and test & track early.
Maybe just catch the infected, and keep them away from the rest of us.

Goverments around the world better learn from this experiance.
(we need testing at borders, and on airplanes too)

You need to follow more news then. There have been constant cases where the virus occurred after a patient was declared cured. The current consensus among experts is that it is not a reinfection, but rather a reactivation. That just means out current method of determining a cured covid19 is not accurate enough.

Agreed. here is a video explaining the immunity situation in different illnesses: https://www.youtube.com/watch?v=ylot5uGyyLA

Yes they need to change it every year and even make an educated guess which vaccine to use. Sometimes it doesn't even work well, sometimes it does. I expect we see something similar with corona in the future. 

Unless they rush this new RNA-vaccine without proper testing and we all die of course :P
