An increasing number of European countries are opting for widespread vaccination against the Mexican flu. Even in countries such as Italy and Sweden, where vaccination of vulnerable groups began last week, all inhabitants are now being called up to receive the vaccine.

In Britain, France and Germany, the general public can be vaccinated at the local GPs from Monday. In Ireland, the Netherlands and Spain, large-scale vaccination will get under way in the first two weeks of November.

After much hesitation, the Norwegian government has also decided to extend its vaccination programme from high-risk groups to as much of the population as possible, starting in late November and early December.
