Smallpox
Because it stops spread of diseases.
Reduced likelihood of catching the disease for which the immunisation was given, and if infected a reduced severity of infection. Immunisation also protects the community (those not immunised) when a certain proportion of the populace is immunised because the disease can not get traction for transmission in the populace.
no because you have it
because they want to be immune from a illness and not die at early age
because there are too many types of the common cold to make a vaccine.
Basically, neither. immunisation prepares the body for the possibility of that infection, and increases the ability of the body to fight it off. It is not a cure, because a cure is applied after the fact and directly acts against the infection; it is not a prevention, because the disease will still happen anyway.
I believe it is because there still is no cure to either disease.
Probably because Australia is an island, with very strict immigration policies.
because the television programmes want to be longer so that is what they do
because the immune system may not be strong enough to create antibodies also when a vaccine is used it could of weakened the immune system ...
Because it has been virtually eradicated and cannot be spread anymore.
Because its TV programmes are watched in Spanish-America, so they have to be spoken in Spanish.
