Which of the following is a substance usually prepared from killed or weakened pathogens?
A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe or its toxins.
What is medicine that contains weakened or dead bacteria and viruses?
Vaccines help reduce the risk of certain illnesses by introducing dead or weakened versions of disease-causing germs (bacteria or viruses) to the immune system.
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.
What is vaccine and its types?
The main types of vaccines that act in different ways are: Live-attenuated vaccines. Inactivated vaccines. Subunit, recombinant, conjugate, and polysaccharide vaccines. Toxoid vaccines.
What is Sue's illness?
In this unit students are introduced to Sue Smith, the eighteen-year-old daughter of Mr. and Mrs. Smith. Sue is a college freshman who is presenting symptoms of an unknown infectious disease which students eventually identify as bacterial meningitis. Sue survives the infection but is left with hearing impairment.
Which of the following is an example of a sequelae?
Other examples of sequelae include those following neurological injury; including aphasia, ataxia, hemi- and quadriplegia, and any number of other changes that may be caused by neurological trauma.
What substance is used to cure or prevent diseases?
Medicines are chemicals or compounds used to cure, halt, or prevent disease; ease symptoms; or help in the diagnosis of illnesses. Advances in medicines have enabled doctors to cure many diseases and save lives. These days, medicines come from a variety of sources.
What type of vaccine is the Covid vaccine?
There are 2 types of approved vaccines: messenger RNA (mRNA) – Pfizer and Moderna. vector – AstraZeneca.
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.
How are attenuated viruses made?
An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent.
Do bacteria use phagocytosis?
Bacteria, dead tissue cells, and small mineral particles are all examples of objects that may be phagocytized. Some protozoa use phagocytosis as means to obtain nutrients.
What are vaccines produced from?
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 tetanus a virus?
Tetanus is an infection caused by bacteria called Clostridium tetani. When the bacteria invade the body, they produce a poison (toxin) that causes painful muscle contractions. Another name for tetanus is “lockjaw”.
What is toxoid vaccine?
Toxoid vaccines Toxoid vaccineA vaccine made from a toxin (poison) that has been made harmless but that elicits an immune response against the toxin. are based on the toxin produced by certain bacteria (e.g. tetanus or diphtheria).
