Washington, Aug 11 (TIWN) The surge in Delta variant cases in the US has also fuelled misinformation regarding vaccines in social media, increasing vaccine hesitancy, media reports said.

These include: vaccines don't work (up 437 per cent), contain microchips (up 156 per cent), people should rely on their "natural immunity" instead of getting vaccinated (up 111 per cent) and cause miscarriages (up 75 per cent).   These claims dipped in May and June when Covid cases plummeted, but with infections soaring due to the Delta variant, the volume of misinformation is also surging, the report said.   "These narratives are so embedded that people can keep on pushing these anti-vaccine stories with every new variant that's going to come up," Rachel E. Moran, a researcher at the University of Washington, was quoted as saying.   "We're seeing it with Delta, and we're going to see it with whatever comes next," she added.
