I'm wearing masks again. I'm not happy about it. It's not required by law, but I'm doing it.
The latest we're hearing is that COVID-vaccinated patients who test positive for the virus rarely get very sick, but their nasopharyngeal viral load is as high as the unvaccinated and infected. The latter, however, tend to get much sicker than the vaccinated because the vaccine better protects the lungs than it protects the upper respiratory tract. What this also means is that COVID-vaccinated persons transmit the delta variant of the virus via fluid droplets passing through the upper respiratory tract just as aggressively as the unvaccinated transmit the virus.
The upshot is that vaccinated people don't have much to worry about by not wearing the mask. Wearing a mask would be more of an act of charity toward the unvaccinated, including those who are afraid of the vaccine and those who belligerently reject the vaccine as a political statement. Many of the latter ridicule those of us who are vaccinated, so it really does take an act of charity to wear a mask not for ourselves but for those who belittle us.
That's something that many docs and nurses have experienced with this pandemic. They must care for people who have demeaned them, dismissed their warnings, and laughed at their pleas to wear masks and vaccinate. But they do it because that is the ethos of a professional. In an ideal world, everyone would have that attitude.
