SEEING RED: Hope is on the horizon for Scotland's threatened red squirrels. A vaccine is being developed to protect them against a deadly disease carried by their grey cousins. The inoculation could prevent the species from being wiped out if a culling programme to kill the invading greys proves ineffective. The vaccine being worked on at the Moredun Research Institute in Midlothian could be ready in five years. Grey squirrels were introduced to Britain from the US more than 100 years ago.
