AT> "The polio vaccine is 90% effective at preventing polio."

AI> That is true after two doses. Three doses are 99 to 100% effective.

AT> "The covid vaccine doesn't prevent covid."

AI> No vaccine prevents disease or virus from infecting someone. It helps your body fight off infection.

First you agreed with me that the polio vaccine is effective at preventing polio, and then you said "No vaccine prevents disease."

It's not a big deal, but you totally contradicted yourself. People do that
sometimes, especially when they're frantically trying to be right about something that they didn't put much thought into.
