The mRNA vaccines were very good at preventing any infection, between 80% and 95% effective depending on variant and study. J&J was between 65 and 80% depending on the variant and study. All of them have been excellent at preventing hospitalization and death.

And they definitely were advertised as helping to prevent the spread. That's the whole "herd immunity" thing. After all, one goal is to prevent the epidemic from hitting the unvaccinated.

Vaccines does not _prevent_ infection.

Vaccines prevent _diseases_ that can be dangerous, or even deadly. Vaccines greatly reduce the _risk_ of infection by working with the body’s natural defenses to safely develop immunity to disease.

You're speaking nonsense. If you mean the vaccine doesn't prevent a virus particle from going into your body, you are correct. They aid the immune system in fighting the virus once it's inside. "Infection" is usually used when some boundary of viral load is crossed, a boundary almost impossible to reach through any means other than internal incubation. Hence, vaccines prevent infection.
