Behaviour change critical in times of corona; a lot is at stake for nations

Sanofi and GSK began human trials on a Covid-19 vaccine last week, and scientists’ projections indicate it could be at least 18 months before a vaccine is ready. Until there is a vaccine, we cannot go back to our normal lives.

Without a vaccine, interventions like social distancing, wearing masks in outdoor areas and hygiene measures have to be in place across the whole society to lower the risk of a rebound of infections. While such interventions have proven to be the most effective at curtailing rapid transmission, their effectiveness hinges on collective compliance.
