Covid vaccines reduce transmission of the dominant Delta variant by about 40 percent, the WHO said Wednesday, warning that people were falling into a false sense of security concerning jabs. Fully-immunised people must stick with measures to avoid catching the virus and passing it on, Tedros insisted, spelling out how the more contagious Delta meant the vaccines were not as effective against transmission. "Data suggests that before the arrival of the Delta variant, vaccines reduced transmission by about 60 percent. The more transmissible Delta variant is now overwhelmingly dominant around the world, having all but out-competed other strains. The WHO has long stressed that the currently-available Covid-19 vaccines are primarily aimed at reducing the risk of severe illness, hospitalisation and death, rather than transmission.
