Global Immunization
|
safest, most effective way of controlling the spread of diseases
|
|
|
What is the one virus that has been eradicated?q
|
Smallpox
|
|
|
Vaccine
|
suspension of organisms or fractions of organisms that is used to induce immunity
|
|
|
Which disease has a 100% mortality rate?
|
Rabies
|
|
|
Herd Immunity
|
occurs when the vaccination of a significant portion of a population (or herd) provides a measure of protection for individuals who have not developed immunity.[1] Herd immunity theory proposes that, in contagious diseases that are transmitted from individual to individual, chains of infection are likely to be disrupted when large numbers of a population are immune or less susceptible to the disease. The greater the proportion of individuals who are resistant, the smaller the probability that a susceptible individual will come into contact with an infectious individual
|
|

|
|
|
What response does a vaccine trigger?
|
Primary response
|
|
|
Which type of vaccine requires less boosters?
|
Live virus (Sabine)
|
|
|
What type of vaccine is used in the US?
|
Killed virus (Salk)
|
|
|
Attenuated Vaccine
|
Live agent which can multiply in the body
*Strongest protection for the longest time *Risk: if it can multiply, it can mutate and revert back to the wild type and the patient can give it to someone else |
|
|
Inactivated Vaccine
|
*a form of the antigen
*killed form *whole viral particle/cell but cannot replicate or revert to the wild type *doesn't last as long as the Attenuated, need boosters |
|
|
Subunit Vaccine
|
*acellular
*entire cell is not there, usually just the most antigenic component *need boosters |
|
|
Conjugated Vaccine
|
*joining of a more potent antigenic compound to the original antigenic agent
*used in young kids *usually a sugar on the surface (antigen) *proteins are the most antigenic, produce the most immune response |
