Introduction:
Vaccination is a biological process in which an individual is immunized against a particular disease-causing agent, in order to prevent a disease. The vaccine is prepared from a killed or weakened form of the pathogen that is similar to the disease-causing agent. This vaccine is injected into an individual in order to induce the immune system against the microbes.
Answer to Problem 1Q
Correct answer:
Measles is emerging and reemerging diseases for which vaccines are widely available.
Therefore, option (b) is correct.
Option (b) is given as “measles”.
Explanation of Solution
Justify the reasons for the correct statement:
Measles is the emerging and reemerging disease because there was a time when measles was fully eradicated from the world but now again measles are becoming the major disease among the population. Measles has a wide variety of vaccination because, this disease was fully curable and scientists have discovered many vaccines for measles, which help in the total eradication of measles
Hence, option (b) is correct.
Justify the reasons for the incorrect statements:
Option (a) is given as “Zika virus”.
Zika virus is the emerging disease that does not have any vaccine till now. However, a number of vaccines are present in the clinical trial. Hence, it is a wrong answer.
Option (c) is given as “Ebola”.
There are no vaccines for Ebola virus disease for humans. Clinical trials of several vaccines are running in different phases. Hence, it is a wrong answer.
Option (d) is given as “C. diff”.
Clostridium difficile is a newly emerging strain of Clostridium, whose vaccines are underdeveloped. Hence, it is a wrong answer.
Hence, options (a), (c), and (d) are incorrect.
Measles is the disease that has been totally eradicated earlier by using the vaccine. So it has a wide variety of vaccines.
