There’s good news and bad news. Let’s do the bad news first.

The outlier-ish superspreader event in Provincetown isn’t the only evidence the CDC has that the vaccinated might be just as contagious as the unvaccinated after they’re infected. A new paper published today looked at cases over the past month in Dane County, Wisconsin, and then across the whole state. Result: The P-town finding is confirmed. The vaxxed had viral loads similar to the unvaxxed, high enough that they should have been contagious to others.

    To determine whether vaccination reduces virus load in the setting of SARS-CoV-2 vaccine breakthrough, we compared the threshold cycle (Ct) value in test-positive specimens collected between 28 June 2021 and 24 July 2021 from 83 individuals in Dane County, Wisconsin, which has one of the highest rates of vaccination among populous counties in the United States [6] and high rates of testing per capita…

    We detected no significant differences in Ct values between fully vaccinated and unvaccinated individuals. Previous studies have suggested that Ct values of ~30 or lower are consistent with the recovery of infectious virus in biological specimens, an indication of potential contagiousness…

    We then expanded the analysis to include 208 additional samples from other Wisconsin counties that are tested by the same commercial laboratory. Considering all 291 samples from all counties (Supplemental Figure 2), there were 79 infections among individuals who were fully vaccinated (Figure 2A). Sixty-six of these 79 (84%) had Ct values ≤30, while 177 of 212 (83%) unvaccinated individuals had viral loads in this range. Moreover, 26 of 79 (33%) of fully vaccinated individuals with breakthrough infections had extremely low Ct values <20, consistent with very high viral loads. Taken together, these data suggest that a substantial proportion of individuals with SARS-CoV-2 vaccine breakthrough infections during our study period have levels of SARS-CoV-2 RNA in nasal secretions that are consistent with the ability to transmit the virus to others.

Yet Biden wants to mandate vaccines and the FDA is getting ready to approve the Pfeizer vaccine.

The rest of the story:

Now let’s do the good news. There’s a second paper out today, this one from Singapore, which also looked at the viral loads in vaccinated and unvaccinated people infected by Delta. Again, they found similar numbers — at first. But then a funny thing happened: (...) PCR cycle threshold (Ct) values were similar between both vaccinated and unvaccinated groups at diagnosis, but viral loads decreased faster in vaccinated individuals.

For the first five days or so after illness, the vaxxed and unvaxxed had similar viral loads. Then they began to diverge:

That graph may help explain why Delta is so contagious in unvaccinated people especially. They’re taking a long time to fully clear the virus from their system, making them infectious to others for two weeks or more. And it also raises a question about the Provincetown and Wisconsin studies: How long did the high viral loads in vaccinated people persist in those cases? The authors didn’t check. Did breakthrough infections linger for as long as infections in the unvaccinated did, or did they last for a much shorter period?

The main issue with the Provincetown outbreak is that a whole bunch of promiscuous gay men were "in close contact" for a prolonged period of time, allowing those short periods of contagion to spread.

The main issue with the Provincetown outbreak is that people who had already taken the jab ended up getting infected and developing Covid.
