Double jabbed people are catching Covid and passing it on to those they live with, warn experts who have studied UK household cases. Individuals who have had two vaccine doses can be just as infectious as those who have not been jabbed. Even if they have no or few symptoms, the chance of them transmitting the virus to other unvaccinated housemates is about two in five, or 38%. This drops to one in four, or 25%, if housemates are also fully vaccinated.
