It has been nearly a year since the A(H1N1) virus made headlines across the globe, despite the relatively small number of victims: approximately 17,000. Mr Osterhaus says the most important difference is that the A(H1N1) virus usually affects younger people, whilst in most cases older people are the ones who die from a flu infection. He says the virus kills more people who would otherwise have a long life ahead of them. For instance, a 70-year-old might have another ten years to live, while one who is 35 might have 45 years remaining. 

Vaccine reserves necessary
The virologist believes that the relatively low number of victims is a result of the worldwide distribution of vaccines and the massive inoculation campaigns. He thinks however that it may prove difficult to organise a similar effort in future. If there is a new outbreak we will have to convince people that the vaccine reserves are really necessary. During the current pandemic we learned how important it is to have good communications. 

The virus is still active on the Southern Hemisphere. South Africa and Australia are working on a vaccination campaign for the winter season. There is also the possibility that people travelling to the Southern Hemisphere will take the virus with them when they return.
