The spread of scepticism and misinformation about coronavirus and the development of a vaccine for it has raised questions about whether it will pose a threat to the goal of achieving widespread immunity.
A report published on Tuesday by the British Academy and the Royal Society for the SET-C (Science in Emergencies Tasking: Covid-19) group said an 80% take up of a jab could be necessary in order for enough people to become immune to the virus and stop its spread. However, the actual threshold will depend on the efficacy of the vaccine, and the 90% achieved by the Pfizer/BioNTech candidate in trials was higher than many dared hope for.
