Kind of a cul-de-sac with that particular poster. He'll post: some vaccinated people still had symptoms when exposed ⟹ the vaccines are fake. And somebody comes along and explains about massive reductions in severity and mortality, and that no vaccine magically prevents exposure, and yes, sometimes you feel your immune system doing the job the vaccine prepped it for. And after a bit he'll come back and post: some vaccinated people still had symptoms when exposed ⟹ the vaccines are fake. Been going on a while now.
