NSW - 34 DEAD - 25 fully vaccinated, page-292

It's not the measles or polio vaccine.. ie a vaccine that actually works. It's a non working vaccine so your argument is moot. A symptom reducer at best.

Nobody is immune to catching and passing on COVID. Vaccinated or otherwise (except those who've recovered from covid already)
The vaccine makes absolutely no difference.
Even half the jab junkies admit this.

If anything a vaccinated person would be more likely to pass on a deadly strain - if their vaccine reduces their symptoms to the point they don't notice them, they'll then be less likely to stay home if sick.
