> vaccines do not stop people from getting infected and infecting others. ... does not mean the people inside can’t get infected so this measure does not help achieve that goal. This is absolutist thinking - "people can still get infected, so this does not help at all" - this not true in the slightest: "it can still happen" is not the same "as it happens at the same rate as before". And "It's not perfect" isn't the same as "does not help". vaccination reduces the rate of infection, a lot, so it does help, a lot. None of this is binary, thinking in absolutes will lead you to false conclusions.
