vaccinologists
They acquired it by becoming infected but surviving the infection.
Pasteur created and tested vaccines for diphtheria, cholera, yellow fever, plague, rabies, anthrax, and tuberculosis.
By the process which scientists look at and try to understand the genetic instructions of disease-causing microbes, in other words DNA created vaccines.

The most prevelent strains of the flu are used to develop the vaccines. These may not be the same strains as the year before. Also, the flu symptoms change due to the atmosphere and climate.
Edible vaccines are vaccines produced in plants genetically modified through bioengineering.
It researches disease trends, vaccines, and the leading causes of death and disability to help develop preventive healthcare measures and products.
No. After you get a disease like smallpox, your body is able to develop permanent defenses against it. This makes you "Immune" to the disease. This is the principle on which vaccines work.
Vaccines do not cause AIDS.
Vaccines are made in several ways. However, all vaccines have the same general goal: weaken the virus or bacteria in a way that allows the recipient to develop an immune response without developing any symptoms of infection. Vaccines are made using the same components that are found in the natural virus or bacteria.Vaccines are made of small amount of the bacteria, virus or other antigen and administered to stimulate the immune system to create antibodies to prevent future infections with the disease.Viruses grows in primary cells, or on continuous cell lines
