There is a reason the Provincetown, Massachusetts outbreak happened and why it is an outlier. Media is extremely reluctant to provide the important detail. I’m not even comfortable bringing it up for how it can be misconstrued because I sincerely don’t intend anything negative toward those who would attend this type of party.
The vaccines do not have 100% efficacy. They help your immune system but they aren’t magic. If you are indoors, packed together like sardines, dancing so as to get you breathing harder while face to face with people you don’t know during a pandemic spike, you’re asking a lot from the vaccine. This is the Tea Dance at the Boatslip in Provincetown where the outbreak happened:
One interesting thing I found in the data from the outbreak was that those who received the J&J vaccine were over represented in breakthrough cases. In the area only 7% of the population had received the J&J vaccine, but 14% of the breakthrough cases where J&J vaccine recipients. I think one of the important takeaways here is that most party goers were vaccinated and zero of them died. Even in doing practically everything to spread COVID, the vaccines still had a 100% rate of keeping people from dying. That doesn't shake my confidence in the vaccines at all. It makes me feel pretty good about it, but I would push people toward the mRNA vaccines.
