Vaccination and Immunity

Tetanus immunization for a person likely to develop the disease (post-exposure) requires passive immunity, which is provided by administering preformed antibodies (tetanus antitoxin). Weakened or dead germs are used for active immunization, which takes too long to develop protection in an emergency.

There is no vaccine to protect against dengue. Developing a vaccine against the disease is challenging. With four different serotypes of the dengue virus that can cause the disease, the vaccine must immunize against all four types to be effective. 

DPT refers to a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus. MMR vaccine is a live attenuated viral vaccine used to induce immunity against measles, mumps and rubella. Dengue has no vaccine yet.

Disease prevention involves a multi-faceted approach, including public health education, immunization programs, and the isolation of infected individuals to break the chain of transmission.

The vaccine is made from a virus either killed, weakened or attenuated, which is introduced into the blood. This process is known as vaccination or immunization. The vaccine can be used to inject the antigen or the antibodies which provide protection against the respective disease by the production of antibodies by the plasma cells. The infectious diseases are transmitted from one infected person to the other person directly. These diseases can be prevented with the help of vaccination.

Bacillus Calmette–Guérin (BCG) vaccine is a vaccine which is primarily used against tuberculosis. In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as close to the time of birth as possible. In areas where tuberculosis is not common, only children at high risk are typically immunized, while suspected cases of tuberculosis are individually tested for and treated.

BCG vaccine stands for Bacillus Calmette-Guerin. It is a vaccine against tuberculosis and for the treatment of some bladder cancers.
So, the correct answer is option A.

BCG, or Bacille Calmette-Guerin, is a vaccine for tuberculosis (TB). It is made from weakened tuberculosis bacteria that infect cows, similar to the human form of tuberculosis. The vaccine is 70-80% effective against the most severe forms of TB, such as TB meningitis in children.

Bacille Calmette-Guerin (BCG) is commonly used against tuberculosis. It is normally given to children as it has been shown to provide very good protection against the disseminated forms of TB in children, including TB meningitis. The other diseases do not have any vaccines yet.

BCG stands for Bacillus Calmette-Guerin. BCG vaccine is given for protection against tuberculosis as a preventive measure. Since tuberculosis is an airborne disease, the person who is infected by tuberculosis should be kept in isolation so that he does not spread bacteria by coughing or sneezing. Also, to protect oneself from getting tuberculosis, one should wear a facemask so that tuberculosis bacteria is not inhaled and does not cause infection. 

BCG, or bacille Calmette-Guerin, is a vaccine for tuberculosis (TB) disease. The BCG vaccine is made from a weakened form of a bacterium closely related to human TB. The vaccine is 70-80% effective against the most severe forms of TB, such as TB meningitis in children.

BCG vaccine provides immunity or protection against tuberculosis (TB). The vaccine may be given to persons at high risk of developing TB. When used to protect against TB, it is injected into the skin. 

Chemoprophylaxis is the method of administrating medicines for preventing disease. It is also called as Chemoprevention. Tuberculosis chemoprophylaxis is used to prevent the infection or it is also used to avoid development of disease in a person who is having latent TB. Isoniazid drug is most commonly given as a preventive measure. 

BCG stands for Bacillus Calmette-Guerin. BCG vaccine is given for protection against tuberculosis as a preventive measure. Isoniazid is an antibiotic used as a first-line agent for the prevention and treatment of both latent and active tuberculosis. Ethambutol is used to treat active TB infection along with other tuberculosis medications, such as isoniazid, rifampicin and pyrazinamide. 

Inoculation is the process of introducing a pathogen or antigen (like a vaccine) into a living organism to stimulate the immune system. Vaccination is the broader term for the act of receiving the vaccine, but inoculation specifically refers to the introduction via injection.
