Destinations will be sorted into green, amber and red categories based on four key criteria: the percentage of their population vaccinated against Covid-19; their rate of Covid infection; the prevalence of new Covid-19 variants of concern; and their access to reliable scientific data and genomic sequencing capabilities.
Additionally, a new "green watchlist" will highlight countries at greatest risk of being relegated from green status to amber, allowing travellers to plan their journeys with greater confidence.
