Question at position 56 Which of the following diseases has be eradicated due to vaccination?Whooping coughMeaslesPolioSmallpox

BlackTom AI · Accepted Answer

The question asks which disease has been eradicated thanks to vaccination, so we will evaluate each option in turn.
Option 1: Whooping cough. While vaccination has significantly reduced the incidence of whooping cough (pertussis) and it remains a public health concern in some areas, it has not been eradicated globally. There are ongoing outbreaks and cases continue to occur despite vaccination efforts, so this statement is incorrect.
Option 2: Measles. Measles vaccination has dramatically lowered case numbers in many regions, and it is a key part of global immunization programs. However, measles has not been eradicated worldwide; outbreaks still occur, and it remains endemic in some countries. Therefore, this choice is not accurate as a globally eradicated disease.
Option 3: Polio. Polio has been eliminated from many parts of the world, and vaccination campaigns have led to dramatic reductions. Yet, polio has not been eradicated globally; there are still endemic areas and occasional outbreaks in certain regions. Hence this is not the correct eradication answer.
Option 4: Smallpox. Smallpox is the only human disease that has been eradicated worldwide through vaccination, with the last naturally occurring case in 1977 and certification of eradication by the World Health Organization in 1980. This makes it the correct choice, reflecting a unique historical achievement in public health.
In summary, the incorrect options reflect diseases that have been controlled or eliminated in certain regions but not eradicated globally, whereas smallpox achieved global eradication through coordinated vaccination efforts.
