They obviously happen but they happen less and when you multiply that over 50,000 people in a stadium then the difference in positive cases that result is significant.I think we see on here everyday people and family members fully vaccinated saying they’ve got Covid, I feel it’s safe to say that breakthrough cases in vaccinated people are far from rare
When we’re being told we need to stop the spread I think the safest way to do that is to also make vaccinated people take a LFT to prove they’re negative as well
just seems common sense
