Nope, slightly before my time.
The swine flu in 1976 resulted in one death and 13 hospitalizations.
One quarter of the US was vaccinated and as you say, less than 50 deaths. As such, the vaccine rollout was stopped. It didn't make sense to continue.
And honestly, 16,000 deaths (which is exaggerated, but we'll go with it) is les than the number of people who will die without the vaccine.
"In people unvaccinated, they were 5 times more likely to become infected, 10 times more likely to be hospitalized, and over 10 times more likely to die from COVID-19."
As far as deaths...684 COVID deaths were reported yesterday. In 30 days, that would be over 16,000 deaths. I really don't understand how you can only look at one side of the equation.
