Exam 1- Immunization Flashcards
What is Immunity?
ability of human body to tolerate presence of material indigenous to body “self” & to eliminate foreign “nonself” material
What is Active Immunity? Give some examples.
protection that is produced by person’s own immune system, usually lasts for many years or a lifetime.
i.e. vaccines
What is Passive Immunity? Give some examples.
protection by products produced by animal or human or transfer to another human.
i.e. in utero, mother’s milk, blood products
What is antigen?
a live (virus/bacteria) or inactivated substance capable of immune response
What is an antibody?
protein molecules (immunoglobulins) produced by B lymphocytes to help eliminate an antigen
What is live attenuated vaccines? Which ones do we commonly use in the U.S.?
- produced by modifying a disease-producing virus or bacterium (does not cause illness)
- can replicate & produce immunity (usually w 1 dose)
- Examples: MMR, varicella, zoster (same virus as varicella but in higher amount), rotavirus, influenza (intranasal)
Live vaccines: can we give them together? Who would we not give it to?
- Give together or more than 4 weeks apart
- immunocompromised
What are Inactivated vaccines?
- cannot replicate
- require multiple doses, 1st dose “primes immune system” & “booster” doses
- antibody titers diminish w time

Pneumonia, secondary bacterial infections, Reye syndrome, myocarditis, death.
MEASLES
Type of pathogen
Symptoms presented with
Complications
Virus
Fever, which increases in stepwise fashion, often peaking as high as 103-105°F. Onset of cough coryza (runny nose), or conjunctivitis. Koplik spots, a rash present on mucous membranes. Maculopapular eruption that usually lasts 5-6 days. It begins at the hairline, then involves the face and upper neck. During the next 3 days, the rash gradually proceeds downward and outward, reaching the hands and feet. The maculopapular lesions are generally discrete, but may become confluent, particularly on the upper body.
Diarrhea, AOM, pneumonia, encephalitis, seizures, death
MENINGOCOCCAL DISEASE
Type of pathogen
Symptoms presented with
Complications
Bacteria
Sudden onset of fever, headache, and stiff neck nuchal rigidity, often with nausea, vomiting, photophobia, and altered mental status.
Petechial or purpuric rash, often associated with hypotension, shock, acute adrenal hemorrhage, and multi-organ failure.

Symptoms presented with
Complications
Virus
Myalgia, malaise, headache, low-grade fever
Orchitis (testicular inflammation), and parotitis
PERTUSSIS
Type of pathogen
Symptoms presented with
Complications
Bacteria
Onset of Kreiser, sneezing, low-grade fever, and a mild occasional cough, similar to the common cold. Cough gradually becomes more severe, and after 1 to 2 weeks, the second or proximal stage begins. Paroxysms of numerous rapid coughs, apparently due to difficulty expelling thick mucus from the tracheobronchial tree. At the end of the paroxysm, a long inspiratory effort is usually accompanied a characteristic high pitched whoop.
