Public officials had known from the early days of vaccine development that vaccinated people could catch COVID-19, but the assumption had been made that they were not going to be spreaders of COVID-19.

It turns out that the delta variant is sufficiently different from the original Wuhan version of the virus that the vaccines work much less well. The CDC performed an analysis of COVID-19 cases arising from one public gathering in Massachusetts. They found that the gathering led to 469 COVID-19 delta cases among Massachusetts residents, with 74% of these cases in fully vaccinated attendees. Massachusetts is a highly vaccinated state, with approximately 64% of the population fully vaccinated.
