There is a lot of focus on whether this child should or even could have been vaccinated against measles. It is impossible to know based on the information. They were due for 0, 1 or 2 doses or MMR vaccine.
At any rate, I would suggest reading it in the other direction: no vaccinated child has died of the measles. Vaccination prevents this disaster. It is likely (but not certain) that many other children were in contact with the same situation which ultimately led to the death of this one. Many of them didn't die because their parents took responsible steps.
In another comment I posted the vaccine schedule for Ontatio. MMR is scheduled at 12 months of age, same as many other places. Your first dose (of the two children need) is only considered "valid" if given on or after the 1st birthday.
However the vaccine is approved as safe and has short-term efficacy when given as young as 6 months. The immunity just doesn't "last" as long when given earlier, which is why its scheduled for 12 months where risk is low. In those communities where anti-vax people congregate, diligent parents can consider giving their children an extra dose at 6 months to cut that risky time in half.
