What is proof that the COVID-19 vaccinations work?

They took some 40,000 people. Half were injected with the vaccine, half with water. No one, including the nurses doing the vaccinations, knew which ones got the real thing.
Four weeks later, they unsealed the information and compared. It turned out that ten days after getting the shot, those who got the real thing stopped getting covid-19. Those who got water kept falling ill.
And that was it, really. Further studies have confirmed this, in a lot of different ways.
