MIC 205 Daydif Exam UPDATED
QUESTIONS AND CORRECT ANSWERS
What does active mean? - correct answer the person is making the immune response
Not getting immune response from someone else
What does passive mean? - correct answer immune response passed from one person to another
Naturally acquired active immunity - correct answer antigens enter body naturally through
infection + immune system produces antibodies and specialized lymphocytes
T/f: immunity length can vary upon the agent - correct answer true
Life-long immunity means? - correct answer once you are exposed to these agents + your
immune system makes antibodies against these, you have immunity for life
Which antigens do we have life-long immunity against? - correct answer chickenpox, measles,
smallpox, yellow fever
Immune system does not build immunity at all to which agents? - correct answer influenza +
pneumonia
Agent enters, immune system mounts response, memory cells do not stay around + are lost. Once
exposed, immune system removes agent. Next time you are exposed, immune system starts from
scratch again
Immune systems loses immunity after a few years to which antigens? - correct answer
diphtheria + tetanus
Need a new shot every 5-7 years
, Naturally acquired passive immunity - correct answer antibodies produced in body of a donor
are naturally transferred into body of recipient
Iga antibodies passed from mom to baby via breastmilk or placenta, last 1 year to 15 months,
eventually antibodies disappear + baby mounts their own immune response
Artificially acquired active immunity - correct answer antigens are intentionally introduced in
vaccines + body produces antibodies and specialized lymphocytes
Artifically acquired passive immunity - correct answer introduction of antibody-rich serum
(blood plasma w/o clotting factors) taken from diseased individual to another susceptible individual
Quick response
Passive = person receives antibodies
Artificial = done in lab or in horse
Get bit by snake, milk snake to get venom, inject it into large mammal like a horse to produce
antibodies to neutralize snake toxin, bleed horse + isolate antibodies, give you a shot of antivenom in
hospital
Passive vs. Active immunization - correct answer passive = start off with injection, antibodies
used up to fight agent, amount of antibodies quickly declines bc person is not building any more
antibodies for 10-14 days
Active = natural exposure or vaccine, start with injection of antigen, mount immune response, but you
need a threshold dose of antibodies in your system to be truly immune + to prevent signs and
symptoms to become asymptomatic. Might need boosters to keep you above threshold concentration
2 types of cancer vaccines - correct answer preventative = used to prevent cancer by targeting
viruses that lead to cancer like hpv + hepatitis b
Therapeutic = used to treat patients with cancer, most are in experimental stage
