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 effective in preventing disease because they?
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
Are made using weakened pathogens?
Vaccines.
What are Weak pathogens injected into your blood called?
Some vaccines are really just a weakened form of the disease. These are called attenuated vaccines.
Do vaccines destroy viruses only?
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.
These are made from destroyed or fragmented pathogens containing a unique protein to trigger an immune response?
vaccines
The preparation of dead or weakened pathogens that causes the immune system to produce anitbodies?
vaccine
Definition of the conventional vaccines?
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)
What is the importance of immunisation and the vaccines given?
To get your immune system prepared if the same pathogens attack your body again.
What does vaccine and pathogenic have in common?
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.
Why its important to grow bacteria in lab?
Cultivation of bacteria is essential for the study of bacteria, usually in the development of vaccines for particular pathogens.
A what is a preparation of weakened or killed pathogens that can prompt the body to produce immunity to a disease?
You are giving the definition of a vaccine but not "what is the following to choose from"
Why is it difficult to find an effective vaccines against disease cause by pathogens that evolve rapidly explain why?
It can be difficult because when the disease evolves your antibodies will not fit the pathogens and you cannot simply have a different vaccine every week as it would be dangerous to your health.
