We certainly didn't lock down society for two years because of covid.

According to Wikipedia on the initial polio pandemic: “On Saturday, June 17, 1916, an official announcement of the existence of an epidemic polio infection was made in Brooklyn, New York. That year, there were over 27,000 cases and more than 6,000 deaths due to polio in the United States, with over 2,000 deaths in New York City alone.[16] The names and addresses of individuals with confirmed polio cases were published daily in the press, their houses were identified with placards, and their families were quarantined.[17] Dr. Hiram M. Hiller, Jr. was one of the physicians in several cities who realized what they were dealing with, but the nature of the disease remained largely a mystery. The 1916 epidemic caused widespread panic and thousands fled the city to nearby mountain resorts; movie theaters were closed, meetings were canceled, public gatherings were almost nonexistent, and children were warned not to drink from water fountains, and told to avoid amusement parks, swimming pools, and beaches.”

Here’s an article with some quotes from people who were young during polio pandemics describing the countermeasures: https://cvm.msu.edu/news/perspectives-magazine/perspectives-...

We didn’t lock down society for 2 years because of Covid either.

You can’t even call the US response a lock down. My friends abroad had to register with the government to leave their homes to visit a neighborhood market.

We didn’t have anything like that.

The US had a more coordinated and stricter response to BLM protests, sending the national guard in to enforce curfews and shooting paint rounds at citizens sitting on their suburban porches.
