Vaccines contain dead or weakened versions of a virus. The body then develops a defense against this virus so that the next time the real virus comes along, the body can identify it and fight it off.
This process of defense development takes place in the immune system of the body. Specialized cells (called b-cells) are created by the bone marrow. These are the cells that produce antibodies. Antibodies work to attack and disable antigens (foreign particles or organisms that have invaded the body, or that the body thinks are invaders). Once the body has developed antibodies for a particular invader, the pattern of those antibodies is stored by the immune system, and duplicates can be readily produced to attack if that invader, or one like it, is detected again. That is what gives you immunity.

What else can I help you with?
Can plasmids or bacteriophages be used in vaccines to fight bacteria?
Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.
What type of cell gives rise to all immune cells?
Hematopoietic stem cells are responsible for giving rise to all immune cells, including T cells, B cells, and natural killer cells. These stem cells are found in the bone marrow and have the ability to differentiate into various types of blood cells that make up the immune system.
Following a primary immune response the cells that give rise to memory cells are?
Following a primary immune response, memory cells are generated from activated B and T cells. These memory cells can recognize the same pathogen if encountered in the future, leading to a faster and stronger secondary immune response. Memory cells are vital for the immune system's ability to provide long-lasting protection against specific pathogens.
What is the ability of a specific immune cell to proliferate and form many generations of nearly identical cells called?
The ability of a specific immune cell to proliferate and form many generations of nearly identical cells is called clonal expansion. During clonal expansion, activated immune cells undergo multiple rounds of cell division, resulting in the production of numerous identical daughter cells that can mount a coordinated immune response against the targeted pathogen or antigen.
Can antigenic proteins from certain pathogen be used for vaccines?
Yes, antigenic proteins from specific pathogens can be used to develop vaccines. These proteins can stimulate the immune system to produce antibodies and memory cells that can recognize and protect against future encounters with the pathogen, thereby providing immunity.
What do vaccines produce?
Immunity via the production of long lived memory lymphocyte cells in the immune system.
What fight disease in your body?
your body has white blood cells which are built up into a immune system these fight the diseases and vaccines boost the system.
Can plasmids or bacteriophages be used in vaccines to fight bacteria?
Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.
What can distroy a virus?
Viruses cannot be destroyed, although doctors can give you vaccines to help fight the virus with your white blood cells in your immune system.
The MHC is important in a T cell's ability to?
The major histocompatibility complex (MHC) is important in a T cell's ability to recognize antigens presented by antigen-presenting cells. This recognition is crucial for initiating an immune response and coordinating the functions of different immune cells. Deficiencies in MHC expression or function can impact the ability of T cells to mount an effective immune response.
Does the immune system often kills cancerous cells?
Yes, most of the time the immune system weeds out cells that are abnormal.
What type of cell gives rise to all immune cells?
Hematopoietic stem cells are responsible for giving rise to all immune cells, including T cells, B cells, and natural killer cells. These stem cells are found in the bone marrow and have the ability to differentiate into various types of blood cells that make up the immune system.

These memory cells can recognize the same pathogen if encountered in the future, leading to a faster and stronger secondary immune response. Memory cells are vital for the immune system's ability to provide long-lasting protection against specific pathogens.
What is the mechanism of interferons in CML?
IFNs increase the ability of the immune system to recognise cancerous or virally infected cells and their ability to kill these cells by various means. Its important to note that IFNs are an older treatment for CML, these days people use TKIs as they have lower toxicity.
What is the ability of a specific immune cell to proliferate and form many generations of nearly identical cells called?
The ability of a specific immune cell to proliferate and form many generations of nearly identical cells is called clonal expansion. During clonal expansion, activated immune cells undergo multiple rounds of cell division, resulting in the production of numerous identical daughter cells that can mount a coordinated immune response against the targeted pathogen or antigen.
What virus attacks the cells in the immune system that produce antibodies?
HIV (Human Immunodeficiency Virus) attacks the T cells, which are a type of immune cell that plays a crucial role in coordinating the immune response, including the production of antibodies. By destroying these cells, HIV weakens the immune system's ability to fight infections effectively.
How do vaccines prevent diseases?
1) Antibodies bind to the pathogen to prevent them from entering or damaging cells 2) Antibodies coat the pathogen stimulating the removal of pathogen by macrophages and other cells 3) They trigger destruction of pathogens by stimulating other immune responses such as complement pathway
