Abstract
The evolution of the HIV following
migratory phenomenons is reported in an interesting study carried on for 15
years. Polymerase Chain Reaction (PCR) is a technique in molecular biology that
amplifies a specific region of deoxyribonucleic acid (DNA), and has been useful
in the molecular characterization of viruses as poxviruses. In many countries, such as Italy,the vaccinations are included in the so-called sanitary
obliged not coercive treatments. This means that the obligation is anticipated
for all the subjects belonging to one determined range of age to undergo some
vaccinations, but these are not subministrated by force in case of refusal. The
legitimacy of the obligatory vaccination against the smallpox, with all the
risks connected, stated that such “risks were too much reduced to be seriously
taken in consideration for the benefits produced on the collectivity”. To ratify this obligation brings, however, to the
reimbursement of the incidental damages produced by the vaccination. Nevertheless, mass
vaccination against smallpox continues to be a leading initiative in western
countries to guard against bioterrorist attack.
