Vaccines can be made from a live microbs that are gentically modified to produced limited infection. they usually harmless and act as good antigens to trigger immune respon because they can multiplying in the body, example of it is mycobacterium bovis to act against tuberculosis. (BCG vaccination)
Vaccines are for the purpose of disease prevention. Vaccination is the process of introducing harmless pathogens to the body for a response trigger without an actual infection. Vaccines are either composed of: *dead pathogens *weakened pathogens *protiens from the target pathogens
Vaccines.
Some vaccines are really just a weakened form of the disease. These are called attenuated vaccines.
Vaccines do not destroy pathogens, they give the immune system antibodies so it can destroy a pathogen before it causes an infection. Vaccines do exist for some bacterial infections.
Conventional vaccines consist of whole pathogenic organisms, which may either be killed or live vaccines; the virulence of pathogens is greatly reduced in attenuated vaccines. This is classified into 2 categories :a)Live or attenuated vaccines; (eg : BCG vaccine)b)Inactivated vaccines (eg : Salk polio & Pertussisvaccines)

To get your immune system prepared if the same pathogens attack your body again.
Vaccines are for preventing infections. Infections are pathogenic (caused by germs). Vaccines help your body prepare to fight specific pathogens, e.g., bacteria and viruses.
Genomic sequencing can help identify specific genetic sequences in pathogens that can be targeted by vaccines. By understanding the genetic makeup of a pathogen, researchers can create more effective vaccines that produce a targeted immune response. Genomic sequencing also helps in monitoring the evolution of pathogens, allowing for the development of updated vaccines to combat new strains.
Gelatin vaccines are effective in preventing the spread of infectious diseases by stimulating the immune system to produce antibodies against specific pathogens.
Cultivation of bacteria is essential for the study of bacteria, usually in the development of vaccines for particular pathogens.
