If anyone watches the Walking Dead (i gave up), they use a trick to pass safely among zombies: They coat their bodies with slaughtered zombie skin parts (yes ew) and walk thru a group of zombies if, oh, say, they happen to take over the village and you're trapped. Not ideal, still can't talk or make sudden movements, but can wiggle thru pretending to be a zombie and you probably won't get murdered.
I think early-vaccinees (sp?) - say in Jan/Feb of this year, when infection rates were raging and very few were vaccinated, had good reason to move like that. Can get through people safely, still not ideal, too many infections around, but still, can now get out of the building.
Now, since more people are jabbed and rates are well down, well, going out means passing mostly non-zombies, only a handful of actual zombies, and anyone can get past a handful of zombies as they aren't very fast. Still, until there are no zombies, gotta be a bit careful, keep that coat of zombie skin on until you're sure you're alone with fellow non-zombies.
Of course, once we get down to no zombies, then no one needs to coat themselves with zombie parts, and we're all good.
I mean this is just science.
