Flu and covid vacines don't prevent the illness. They just "maybe" soften their impact, but even that is not guaranteed as virus mutates fast. Don't throw them into the same bag as truly life changing polio or smallpox vaciness.
Millions of people died from covid. It's not the flu. Vaccines don't just "maybe" reduce the impact, they DO reduce the impact. It's extremely well documented. Even now, with the milder strains of covid that are common, it still reduces your chance of hospitalization and death by 57%.
