Will the Vaccines Work in the Real World?

We know from the that the trial data, that they are preventing severe disease. But we haven't really been able to show from the studies that have been done that they're actually stopping people spreading it. So you might still get infected after you've been vaccinated. You don't get seriously ill, but you can still pass it on. That surely massively changes the picture, depending on exactly the impact it has on transmission. It's one of the large uncertainties around the vacinas now,. particulalyr around astrogenica vaccine, where we have less clear data and whether it protects against infection and therefore transmission. And we're really going to have to monitor as the vaccine is rolled out
