In 1980 smallpox was considered disappeared worldwide. However, the United States and Russia, as the raw material for making vaccines in case of disease recurrence, preserved samples.
Now, the US government fears that Iraq will have samples of baztan and use them as a biological weapon. To combat it, he has decided to incorporate first the military and then the emergency services personnel. In addition, by 2004 they have proposed that everything they want be integrated in the US.
The vaccine, however, has side effects worth considering: one in every million people can die, one in every 300,000 can suffer encephalitis and is also harmful for people with poor immunity and skin problems.
And all because they are frightened by a possible biological attack.
