What substance does a vaccination stimulate your immune system to produce?
Vaccination increases the levels of circulating antibodies against a certain antigen. Antibodies are produced by a type of white blood cell (lymphocyte) called B cells. Each B cell can only produce antibodies against one specific epitope.
What is another name for vaccination?
This is why the term vaccination is closely associated with immunization. Another closely related term is inoculation, which refers to the process of introducing a substance like a vaccine into the body to boost immunity.
What is a vaccine simple definition?
Definition of Terms
Vaccine: A preparation that is used to stimulate the body's immune response against diseases. Vaccines are usually administered through needle injections, but some can be administered by mouth or sprayed into the nose.
What is an attenuated microorganism?
Weakened, or attenuated, vaccines consist of microorganisms that have lost the ability to cause serious illness but retain the ability to stimulate immunity. They may produce a mild or subclinical form of the disease.
How does a vaccine activate the body's immune system?
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.
What's a synonym for virus?
Synonyms & Antonyms of virus
as in disease, cancer. Synonyms & Near Synonyms for virus. cancer, contagion, disease.
What is another word for herd immunity?
Herd immunity (also called herd effect, community immunity, population immunity, or mass immunity) is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through previous infections or vaccination ...
How do vaccines work?
How vaccines help. Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.
What is vaccine in biology?
A vaccine is a biological substance designed to protect humans from infections caused by bacteria and viruses. Vaccines are also called immunizations because they take advantage of our natural immune system's ability to prevent infectious illness.
What are vaccines made of biology?
Vaccines are made up of whole bacteria or virus, or parts of them, often a protein or sugar. These active components of the vaccine, called antigens, are what trigger an immune response when in the body.
Is a vaccine a drug?
Monitoring of Safety and Effectiveness
It is important to note that a vaccine is a drug. Like any drug, vaccines have benefits and risks, and even when highly effective, no vaccine is 100 percent effective in preventing disease or 100 percent safe in all individuals.
What is toxoid give example?
Toxoids are used extensively in the production of vaccines, the most prominent examples being the toxoids of diphtheria and tetanus, which are often given in a combined vaccine. Toxoids used in modern vaccines are commonly obtained by incubating toxins with formaldehyde at 37° C (98.6° F) for several weeks.
What is attenuated infection?
The author considers attenuated infection to be a "state of truce or peaceful coexistence between the host and the infecting agent." This phenomenon is manifested in the carrier state, microbial persistence, and latent infections.
