By the time the virus reached the U.S., the country already had a vaccine ready.

70,000 to 116,000 died in the estimate, in the USA
Fortunately, we had some great, persistent scientists who had a Flu vaccine ready, by September 1957, the month this flu first hit the U.S.
And they had the insight to know the flu in Asia in January would be a pandemic and hit the USA by the Fall of 1957.
Influenza vaccinations were created in the 1940's, so in 1957 they had the experience and knowledge of how to make the vaccine...
Holy Toledo, that was one deadly flu, considering we had a vaccine by the time it reached the US....
BUT as they say, vaccines do not save lives, vaccinations do.... And it takes time and supplies and a willing populous, to get people vaccinated.
The Corona virus, any form of it, not just COVID 19, has never had a vaccine created for it, that works.... So we are in a worse position than they were in 1957....
A corona virus is NOT an Influenza virus, and this is more difficult...
And this corona virus, has no 'season' where it slows down or dies off, like an influenza virus....
