> There are very, very few people who cannot take these vaccines due to allergies etc That is correct, allergies are very rare. I'm talking about patients whose immune system is weakened, either on purpose, e.g. transplant patients, or because they have an auto-immune disease (HIV etc.) or simply because their immune system is weak as a result of another disease (e.g. cancer) or they were simply dealt a weak immune system at birth (genetics) or their immune system is weak because they are very old. Then add infants, children and pregnant women who can't get vaccinated in the majority of cases. Now add the whole anti-vaxx crowd, people who became the victim of FUD, people who simply don't care, people who don't get their second shot, and it doesn't look very good, does it? > The actual group safety arguments never come with concrete numbers to assist with the underlying intuitions and that is suspicious. There are plenty of models to give you concrete answers, but there is even more uncertainty in the model assumptions, so we simply don't know with certainty. In any case we are already starting to find out in different countries.
