77% still quite a bit better than flu vaccines (40-60) but not nearly as good as some like measles (~97). They basically eradicated polio but that was 99-100% after three doses.

77% is the effectiveness against hospitalization. Effectiveness against infection and transmission tends to be lower. To stop the spread, what matters is effectiveness against transmission. And since there are animal reservoirs for COVID, it will not be eradicated.

  So is the 77% comparable to the effectiveness of polio vaccine? Or has the meaning changed. If a lot of these vaccines leave people walking around with no symptoms but still infectious it's a miracle they ever eradicate anything. It's starting to make sense why most diseases are still around actually.

    My understanding is that for the polio vaccine, the effectivenesses are the same, but they are not for the COVID vaccine. I would appreciate it if someone could explain this.
