The measles vaccine is not perfect either. The only reason we don't have to worry abour measles is because enough people have been vaccinated to achieve herd immunity and bring down the transmission to zero. However, if vaccination rates drop even a little bit then outbreaks can pop up again because measles is extremely contagious.

Like last years flu vaccines, the current covid vaccines are targeting last years version of the virus, since then the virus has evolved to escape the vaccine[0]. 100% uptake of the current vaccine won't eliminate the virus.

I encourage everyone eligible to get vaccinated, but since the vaccines don't reliably prevent transmission there will be no significant herd immunity effect.

But in cases when that's happened, how many people caught "breakthrough" measles, as opposed to unvaccinated people catching measles?

Not exactly what you are asking, but close enough: From https://en.wikipedia.org/wiki/Measles_vaccine

> This is often done at age 15 to 18 months. After one dose at the age of nine months 85% are immune, while a dose at twelve months results in 95% immunity.

This graphic is interesting https://en.wikipedia.org/wiki/Measles_vaccine#/media/File:Me... With one dose the case number is reduced a lot, but there are still some smaller peaks aver few years. After the second dose was made mandatory, the number of cases goes to almost zero.

I'm not sure about Canada, but here in Argentina kids get two doses, and every 5-10 years there is a effort to give an additional dose to some groups with more risk (like small children).
