The world health organization says covid vaccines reduce virus transmission by about 60 percent.
But with the arrival of the Delta variant it drops to only 40 percent. Nwa show chief tedros and gabriele warned that people were falling into a false sense of security the vaccines have ended the pandemic. They urge people to continue to take precautions to avoid catching or spreading Covid-19 even if they are vaccinated vaccines save lives. But they do not fully prevent transmission. If you’re vaccinated you have a much lower risk of severe disease and death. But you’re still at risk of being infected and of infecting others.
