Do coronavirus vaccines prevent transmission of the virus?

Studies show that while both the vaccinated and unvaccinated can have similar levels of the virus in their bodies, the vaccinated are less likely to pass it on to others. Plus, ‘COVID toes’ and a pill to treat COVID at home.
It has long been established that COVID-19 vaccines reduce the risk of serious illness and hospitalisation. But there has until recently been a question mark over whether they reduce transmission of the virus.
It is an important question and one around which public health policies have been built. The United Kingdom, for example, has mandated COVID vaccines for all social care staff to protect the vulnerable people they care for; they are set to do the same for NHS staff. And in Italy, from October 15, workers will have to show proof of vaccination, a negative COVID test or recovery from a recent infection to their employer. Anyone unable to do this risks being suspended from work without pay. Other countries are adopting similar measures.
But do vaccines actually limit the spread of the virus?
