So this magic vaccine will work on all future mutations of Covid-19?
The futures is uncertain.
The 1918 flu never went away, all seasonal influenza is derived from it, and apparently the nastiest mutations from that one happened in 1957, 1968 and 2009.
However none of those were as bad as the orginal 1918 flue. Which killed 50 to 100 million people worldwide.
Who knows when the next really deadly mutation of Covid will happen, maybe next year? maybe 30 years from now??
"That’s what happened in 1957 when the 1918 flu, which is an H1N1 virus, swapped genes with another bird flu giving us the H2N2 pandemic, which claimed a million lives worldwide. It happened again in 1968 with the creation of the so-called “Hong Kong Flu,” an H3N2 virus that killed another million people.
The so-called “Swine Flu” pandemic of 2009 has an even deeper backstory. When humans became infected with the 1918 pandemic flu, which was originally a bird flu, we also passed it on to pigs."
“We’re still living in what I would call the ‘1918 pandemic era’ 102 years later” says Taubenberger, “and I don’t know how long it will last.”
