Yea it is good news but or was always likely to be the case. I did get tired of reading so many pronouncements.on here about how vaccines only stop you getting very ill and don't stop you catching or transmitting Covid as if that is fact.
It has never been fact, it was just not clear and given how many vaccines ( though admittedly not all) do in fact significantly reduce infection and transmission , it seemed very likely to me that the Covid ones would too.
It is very good news though.
