The highly contagious Delta variant has reduced the effectiveness of vaccines against the transmission of Covid-19 to 40%, announced the boss of the World Health Organization (WHO) on Wednesday, November 24. THEns a regular press briefing devoted to the pandemic, which is wreaking havoc in Europe, Tedros Adhanom Ghebreyesus calls on the populations to continue to wear masks and other barrier measures. “Vaccines save lives, but they do not completely prevent the transmission of Covid-19”, did he declare.

“There is data to suggest that before the arrival of the Delta variant, vaccines reduced transmission by about 60%. With Delta, that dropped to 40%.”, he stressed. “In many countries and communities, we fear that there is this misconception that vaccines have ended the pandemic, and that people who are vaccinated no longer need to take other precautions.”, he added.
