Do you really believe that?

I don't know about the supposed meningitis vaccine as the genesis of the Spanish Flu. But I can tell you that they did develop a vaccine against Spanish Flu in 1918 and it basically did nothing at all to halt the spread of the virus. Go look it up.

Looking up, there was no flu vaccine really developed until 1938. They were trying, created something, did not worked, it was not used.
Nobody got it!
Blaming the dead’s for faulty vaccine is total Bull.
People died of the flu, not of the vaccine!
Why?
Because nobody got any vaccine to speak about!
There were no vaccines to speak about in 1918! Only Smallpox, cholera, plague, rabies.
But the horrendous toll of the flu spurred the vaccination efforts. Sort of like last year. It only took them 20 years then.
They were using masks then though! With similar results.
