00:00However, now we are dealing with the Delta variant, which is really quite a lot more transmissible than the Alpha
00:08variant, number one.
00:10Number two, the data are clear, the most recent data, that when a person gets infected, who has been vaccinated,
00:18namely a breakthrough infection,
00:19and they get infected with the Delta variant, that the level of virus in their nasopharynx is about a thousand
00:27times higher than with the Alpha variant.
00:30And it has been well documented that even though it's a rare occurrence, those individuals can and have transmitted the
00:39virus to uninfected individuals.
00:41And for that reason, the recommendations and the guidelines have been changed to say that if you are vaccinated, even
00:49though you are vaccinated,
00:50you are in an indoor public setting in an area of the country with a high degree of viral dynamics,
00:58namely the red and orange sections on the CDC chart, then you need to wear a mask, even though you
01:05are vaccinated.
