See my other responses. Obviously this is bad. But the current measles outbreak is a symptom of a problem that's been happening over the last 1 or 2 decades. It literally CANNOT be caused by this, neither in the US or Canada.

It's still not too late for anyone who is unvaccinated to get the vaccine! Hopefully the next administration undoes this change, but the really important part is managing to shrink the anti-vax movement (which, if you look at the data in my other comments, you can see has been a problem since before Trump).
