After some research I found the important parts mostly bolded
Advantages:
1) Although the technology at first seems like something done for convenience rather than being something of significant utility, the fact is that poorly developed nations like India which have a relatively poor vaccination program are most likely to benefit from such a vaccine.
This is also the reason why many of the projects mentioned here (including Arntzen's early work) have been funded by the WHO.
2) Mucosal immunity : The vaccines which are given parenterally (e.g. Intramuscularly) induce a systemic response but little or no local immune response in the GI tract. This so called "mucosal immunity " is increasingly being considered very important for defense against GI pathogens. ( Remember OPV..)
3) And of course, it's painless and convenient
Disadvantages:
1) The vaccine dose would be inadequate if the patient eats only one banana/potato instead of the recommended two. Furthermore, there might be difficulties in judging the dose itself since the amount of antigen in each fruit cannot be accurately measured.
2) The risk of introducing a new gene into the Plant DNA population is not known. The gene may jump species and propagate into other plants (or wild varieties of the same plants).
This may cause unpredictable results including a decrease in the number or even extinction of a particular plant species due to growth stunting caused by the viral/bacterial gene. (This has been known to occur in research studies, including Arntzen's)
3)"Oral Tolerance": In another concern, scientists need to be sure that vaccines meant to enhance immune responses do not backfire and suppress immunity instead. Research into a phenomenon called oral tolerance has shown that ingesting certain proteins can at times cause the body to shut down its responses to those proteins.
This may cause the body to become more susceptible to a particular disease agent rather than become immunized against it.
Answer:
C. Acute Epiglottitis
Explanation:
Before explaining why C is the correct answer, let's look at why the others are <u>not</u> correct:
- A. GABHS is a bacterial infection that is a type of streptococcus (aka Strep). It is also the most common cause of Tonsillitis! Symptoms of GABHS typically include: Sore Throat, fever, swollen lymph nodes, and tonsillar exudates. It sounds very like what we're looking for, but notice drooling isn't a symptom found with this one!
- B. Acute Tracheitis is inflammation of the trachea often resulting from a bacterial infection. Symptoms of this condition are more breathing-related such as severe dry cough, wheezing, and even shortness of breath and cyanosis. Not what we're looking at.
- D. Acute Laryngotracheobronchitis is a common disease found in young children that is more commonly known as Croup. This disease is most often characterized by a "barking cough." Other symptoms include fever, stridor and hoarseness.
Now, WHY is C the correct answer?:
Acute Epiglottitis is, like croup, commonly found in younger children and is defined as inflammation of the epiglottis (the flap that covers the trachea when swallowing). It is often characterized by fever, sore throat, difficulty swallowing, and (more specifically) drooling! The drooling coupled with the clear bilateral breath sounds and absence of a cough help to diagnose this illness.
Explanation:
commercial , elevator pitch & a brief or summary are very similar
summary that over do it tend to be funny
commercials tend to be funny so
a commercial that over summarizes & exaggerates may do the job
