Can anyone shed some light on this study?

I understand it was published nearly a year ago and was probably helpful to try and encourage people to stick to the lockdown but I'm intrigued as to how they can prove people with immunity can still transmit covid without being infected?

Honestly, I don’t know…

Especially because the study they are talking about is about infections and reinfections….

The way I understand it is that the particles of the disease could still go up your nose and end up in the back of your throat, but because of their immunity and antibodies springing into action, they will never actually become infected themselves, but they could still possibly pass it on, ie sneezing and coughing while they have infectious particles in their nose/ throat, which could still infect others
