Efficacy of covid vaccines fell to 40% due to Delta variant: WHO

Mexico City.- The highly contagious Delta variant of the coronavirus reduced the effectiveness of vaccines against the transmission of the disease by 40%, the WHO chief stressed on Wednesday, urging people to continue wearing face masks and to respect healthy distance measures.

“Vaccines save lives, but they do not totally prevent the transmission of covid-19,” explained Tedros Adhanom Ghebreyesus at a regular press conference on the pandemic, which is wreaking havoc in Europe.

The director of the WHO assured that there is data that suggests that before the arrival of the Delta variant, vaccines reduced transmission by 60% but, with the appearance of this variant, they fell to 40%.

In many countries and communities, we fear that there is a misconception that vaccines have ended the pandemic, and that vaccinated people no longer need to take further precautions, “he added.
