Vaccination Curbs Covid-19 Transmission

Doctors in Cambridge University have found that a single dose of the Pfizer Covid-19 vaccine markedly reduces asymptomatic infections in health workers (https://www.theguardian.com/society/2021/feb/26/single-pfizer-jab-can-reduce-asymptomatic-covid-infections-by-75). There was a 75% fall in infections within 12 days of being vaccinated. This appears to be evidence that this vaccine can protect the treated individual and people that they might (in their work) transmit the disease to. We need much more evidence but it looks as if vaccines can curb transmission.
