United Kingdom 🇬🇧: Scientists in the United Kingdom have started to develop vaccines as "insurance" against a new pandemic caused by an unknown dubbed "Disease X".

Scientists have drawn up a list of animal virus threats that are capable of infecting humans and may, in the future, spread rapidly around the world.

Which one will break through and trigger the next pandemic is unknown, which is why it is referred to only as "Disease X".

Broadcaster A Sky News had access to the laboratory and was escorted around the site, which is run by the UK Health Security Agency.
