Saying it's happened in the past isn't an argument that it should continue in the future. I doubt your swine flu nasal spray had as intense of negative side effects as the COVID second shot and booster tend to in the young and healthy. Now that we're in booster territory and Delta is being phased out the shots are almost certainly more painful than the disease for some portion of the population.

I can't recall any other health based requirement for attending an event or restaurant. I also don't understand why people continue to harp on how a personal COVID vaccination decision "affects society and others" at this point. The vaccine only marginally prevents infection at this stage, and the primary benefit of reduced severity should stop everyone who's vaccinated from worrying about what others around them may be doing. I get the flu shot so I don't get the flu, and I'm not sitting around telling others who haven't that they're putting me in danger.
