It didn't have to be this way. Our government & public health officials didn't need to gamble like this.
The choice isn't between going back to lockdowns or stopping all public health interventions for a novel pathogen against which only 64% of the pop. is immunized.
We live in Canada. If we don't have enough resources (and man power) to manage a once in a century public health emergency, where do they have the resources?
We could have continued testing/tracing/isolating, we could have added on rapid tests, undertaken airborne mitigation strategies with better masks/ventilation/filtration, we could have paid people to take time off when sick.
We could be incentivizing vaccines with something as small as a grocery store voucher, we could be implementing vaccine passports, we could mandate vaccines for health care workers, or we could be do ring vaccinations for outbreaks.
Don't let them fool you into thinking they're taking a brave libertarian stance for freedom or some sort of forward-thinking economically focused strategy.
Look around at the world and see what is possible.
And then look what our province is offering us. #covid19ab#ableg

Second, we know the virus is characterized by super spreading events and is highly overdispersed (so 80-90% caused by just 10-20% of people). So cases will be clustered & I suspect it follows that breakthrough infections will also be clustered.
We can't use this 1 small sample size of interconnected cases (with potentially the same source of exposure or same environmental conditions, ie. ventilation) to make VE determination. That's where the UK data is so helpful & far more reliable! For now, it's our best info source.
