"No clinically severe COVID-19 (1) was observed, and no patient was hospitalized" In other words, this case study is a relatively ordinary result in line with what we know: that the major COVID-19 vaccines greatly reduce the chance of severe illness but leave nontrivial chance of infection and transmission.
What’s more interesting is that 0/6 of the miners who had natural immunity were re-infected. That points to natural immunity preventing spread. The fact that vaccinated individuals don’t stop transmission means that there is no “public good” from getting vaccinated, it’s solely for personal benefit. Vaccine mandates or checking for vaccination status are pointless because of this.
No such fact exists.
