Lovely news.
A couple of things I would like to mention and with any hope some might see the same as I do, as it is there if you look not in the right places but from the right place itself.
1.
It has been said here that the 1918 pandemic ripped through the world and is one of only two reasons why viruses leave us. Only a third of the world's population were infected a hundred years ago, no where near the numbers in order to give the herd immunity, something like seventy percent is expected to be the current requirement. So this can't be one of the two.
2.
With no vaccine for the Spanish outbreak there has to be a third addition. Number three is where it is at for me and our third wave I would hazard a wager will be in between one and two in terms of severity and the last one we have to number.
It must be a balance thing, it comes so quickly and changes constantly which is beyond fast and almost unearthly, money says the exit will follow suit.
