Troll accounts that had attempted to influence the US election had also been tweeting about vaccines, a study says.
Many posted both pro- and anti-vaccination messages to create "false equivalency", the study found.

Earlier this month, the World Health Organization (WHO) said cases of measles in Europe had hit a record high, with experts blaming this surge in infections on a drop in the number of people being vaccinated.
