Masks and vaccination have a central role in minimising the health and economic impact of COVID-19, regardless of the long-term strategy we use against the pandemic. These interventions depend on both good performance and high population coverage. Here we update evidence on mask effectiveness and make the case that mask use needs to be universal in all indoor environments at Alert Level 2, including workplaces, schools, and high risk settings such as gyms.
