There are early signs that people who have been vaccinated against Covid-19 may be able to transmit the Delta variant of the virus as easily as those who have not, scientists at Public Health England (PHE) said on Friday.
The findings chime with those from the US Centers for Disease Control and Prevention, which last week raised concerns that vaccinated people infected with Delta could, unlike with other variants, readily transmit it.
The highly infectious Delta variant has become the dominant coronavirus type globally, sustaining a pandemic that has already killed more than 4.4 million people.
