Vaccine-Table 1 Flashcards
What is immunity?
the ability of the human body to tolerate self and to eliminate foreign (“nonself”) material
What is the immune response?
a defense against the antigen
usually involves the production of protein molecules by B lymphocytes
What is active immunity?
Protection that is produced by the person’s own immune system. This type of immunity is usually permanent.
What is passive immunity?
Protection by products produced by an animal or human and transferred to another human, usually by injection.
When are antibodies transported across the placenta?
last 1-2 months of pregnancy
What can be given for post-exposure prophylaxis for Hep A and measles?
Homologous pooled human antibody (immune globulin)
What can be given for post-exposure prophylaxis for Hep B, rabies, tetanus, and varicella?
Homologous human hyperimmune globin
What can be used to tx botulism and diptheria?
Heterologous hyperimmune serum (antitoxin)
What are monoclonal antibodies produced from?
Single clone of B cells
What are monoclonal antibodies used for?
Diagnosing certain types of CA, tx of CA, prevention of transplant rejection, and tx of autoimmune dz
What monoclonal antibody is used for prevention of RSV?
Palivizumab
What are ways you can obtain active immunity?
Surviving infection and vaccination
What factors influence immune response to vaccination?
Presence of maternal antibody Nature and dose of antigen Route of administration Presence of adjuvant (aluminum-containing material) Host factors
What are live attenuated vaccines produced from?
Produced by modifying a disease-producing (wild type) virus or bacterium
Resulting organism retains ability to grow and produce immunity but usually does not cause illness
What are inactivated vaccines composed of?
whole viruses or bacteria or fractions of either (protein based or polysaccharide based)
What are the protein based inactivated viruses?
Toxoids (inactivated bacterial toxin)
Subunit or subviron products
What are the polysaccharide based inactivated viruses composed of?
pure cell wall polysaccharide from bacteria
Why are severe rxns possible in live attenuated viruses?
uncontrolled replication in pts with immunodef
How are live attenuated viruses destroyed?
By heat and light
What are the viral live attenuated vaccines?
Measles, mumps, rubella, vaccinia (small pox), varicella zoster, yellow fever, rotavirus, intranasal influenza, oral polio
What are the bacterial live attenuated vaccines?
Oral typhoid vaccine
How many doses does an inactivated vaccine typically require?
3-5 doses
First dose primes immune system, immune response develops after 2nd or 3rd dose
The immune response to inactivated vaccines is what?
Usually humoral
What are the viral whole cell vaccines?
Polio, hepatitis A, rabies
