Less of an issue, not no issue at all.It is that simple. Breakthough cases will not going to a hospitalisation because of vaccination. Again, having covid is not an issue if your are vaccinated, which is not true when you are not.
A lot less of an issue for sure.
Reduction, not force field.
Some number of unvaccinated will allow COVID to spread creating a baseline transmission rate. Some small percentage of vaccinated will be breakthrough cases, a reduction based on that baseline transmission not zero. Some small percentage of those breakthrough cases will need hospitalization. Some small percentage of those who need hospitalization will die.
Base rate * reduction * reduction * reduction = Unlucky few.
For those in the unlucky few, it doesn't matter that the triple reduction made the number statistically small. To them, and their families, the only thing that matters is that the base rate was to high for the triple reduction to make it actually 0 and the impact to the rest of their lives (or lack of life) will be devastating.
And, that's why I'm angry. At this point, those who choose to be unvaccinated are just fine causing that impact.
You can play with the 3 reduction rates and get different numbers of vaccinated that die anyway. But, no matter what percentages you use for each, there's always one truth. The larger the first number is for the base rate of cases, the larger the last number will be.
It's definitely a small number relative to the first. But, that first number for the base rate is still so high that the last one is a meaningful value above 0.
