Children mustn't see grandparents until vaccine found?

[Witterywoman]

Now that the kids are back at school, SIL has said her kids must isolate from both sets of grandparents in case they give them Covid picked up at school, and this must continue until a vaccine is found. All 4 grandparents are over 70 but healthy, no health conditions to speak of. My parents are particularly upset and don't understand it. I don't get it either and don't intend to stop them seeing my kids.

Are we missing something?

I honestly can't see why so many people are ruffled by this someone has made a decision to keep their elderly parents/in laws safe and people think she is a dictator for this?! when children go back to school they are going to be more at risk of potentially passing something on to someone vulnerable. There is no arguing with that. I wonder if this people that are cross about that are so because they have some guilt that they are knowingly going to continue to visit their elderly or vulnerable relatives [/quote]
Because I dont need to be 'kept safe' without a discussion about it.

I'm not stupid and I'm not senile.
