Except they didn't say vaccinated people no longer have to wear masks inside because ventilation systems suddenly got better. Several months ago, studies started showing that the vaccines do a really good job of preventing people from getting COVID even if they are exposed to it. And the vaccines are also preventing the vaccinated from being carriers and spreading COVID to others. Neither of these findings change when you enter a crowded poorly ventilated bus. Not that I would ever want to do that anyway. I have always avoided crowded poorly ventilated spaces simply because they are terribly unappealing to me.
