I never said they weren't susceptible to getting a cold I said they wouldn't catch it every time they encountered a child with a cold and they're even less likely to catch it after getting the flu vaccine.

You are acting like this is a normal thing but this has only become the normal after covid. After covid everyone is paranoid about the slightest sickness and its coming at a cost of education. Before covid parents would make a decision on if their kids were sick enough to justify staying home.

After covid the sick days have doubled in the span of a year and more compared to pre covid. I'm stating that the benefit of teachers not encountering as many sick children is not worth the amount of time of school children are having. My reasoning is firstly that advising kids to stay home does not stop teachers from encountering sick children it only reduces the likelihood. Secondly a teacher does not get sick every time they encounter a sick child so if they have sick children in their class they will be fine for most of the year. They might get sick once or twice over winter despite encountering sick children every day.

How about you provide some reasoning as to why you think that it's a good thing kids sickness rates have doubled in the past year.
