Why don’t you do some real research on the Spanish Flu.
I suggest your read:

The Great Influenza: The Story of the Deadliest Pandemic in History by John M. Barry

Pale Rider: The Spanish Flu of 1918 and How It Changed the World by Laura Spinney

After you do, you’ll realize just how wrong this article you posted is.
There is no doubt that pneumonia killed many during the Spanish Flu but the pneumonia was a opportunistic infection of those who had already been attacked by the influenza virus. IOW, first you got the influenza and then you got the pneumonia.
BTW, the virus causing the influenza has been isolated and studied for years.

Here is a research article from the Frontline Doctor, Dr Frederick Gates, on the ground treating soldiers. Do you disagree with his research?

I recall a story of how victims buried in tbe arctic were exhumed in an attempt to recover the intact virus.
