1918 Spanish Influenza epidemic could happen again

“An international team of researchers has shown that circulating avian influenza viruses contain all the genetic ingredients necessary to underpin the emergence of a virus similar to the deadly 1918 influenza virus.”

“Critically, the research provides additional insight and evidence for the mechanisms responsible for adaptation of avian influenza viruses to mammals. One mutation in the novel transmissible 1918-like avian virus, for example, is responsible for increased virus growth in mammalian cells. Mutations in hemagglutinin, a protein found on the surface of influenza viruses that binds to host cells, alter the protein’s stability, a change that could potentially enhance the virus’s ability to infect the upper respiratory tract of humans.”

“”With each study, we learn more about the key features that enable an avian influenza virus to adapt to mammals and become transmissible,” says Kawaoka. “Eventually, we hope to be able to reliably identify viruses with significant pandemic potential so we can focus preparedness efforts appropriately.”

Depends. There is one theory that places 1918 as the trigger date because the US army introduced mandatory vaccination. Compelling, given the timings.

Vaccines in 1918 America.

Timings and why it affected the young and able;

“There was seven times more disease among the vaccinated soldiers than among the unvaccinated civilians, and the diseases were those they had been vaccinated against. One soldier who had returned from overseas in 1912 told me that the army hospitals were filled with cases of infantile paralysis and he wondered why grown men should have an infant disease. Now, we know that paralysis is a common after-effect of vaccine poisoning. Those at home didn’t get the paralysis until after the world-wide vaccination campaign in 1918.”

Easily provable.

“The origins of this influenza variant is not precisely known. …However, a first wave of influenza appeared early in the spring of 1918 in Kansas and in military camps throughout the US.” ~Stanford
