What makes swine influenza dangerous is that just like most influenza viruses it undergoes the process of antigenic drift. When spot mutations occur on the hereditary material which causes modifications in the physiological make-up of the virus.
These small changes are what frustrate scientist's attempts to create the vaccination for flu.

The 'H' means hemagglutinin which is a protein that binds the bronchial flu virus to the cell and injects its material. The 'N' stands for neuraminidase that possesses a number of technical enzymes that cause the infected cells to release the viruses that are newly formed.
All these elements of influenza make it very dangerous. Before the winter occurs, Although the shape that's currently dispersing is mild it may still turn right to a strain from the next month or two.
The fact that it is also an illness means there isn't any current vaccine to the virus. If it becomes deadly, we'll have no protection against it except for those given by generic antibacterial drugs.
