This is an interesting observation.
Vaccinated party-goers avoided virus, NSW Gov says
The NSW Government says the highly contagious Delta strain of COVID-19 infected everyone who attended a Sydney birthday party except for the six people who were vaccinated.
24 of the 30 attendees of the West Hoxton party, and many of their household contacts, have all tested positive for COVID-19.
Here's NSW health minister Brad Hazzard from earlier today:
"To emphasise just how important vaccinations are … not one of those 24 people were vaccinated.
"I can also advise that six health workers who attended the party, who were fully vaccinated, not one of those people has been infected.
"Obviously, it's an unfolding situation … but the early and strong indication from that party are if you're vaccinated you are much more likely to not be infected with COVID-19.
"Short message is, get vaccinated."

Maybe that's one to strike off the list above, Trev?
