Last year, the United States introduced compulsory vaccination for all children of a certain age against rotavirus. Without the vaccination, rotavirus hospitalized 55,000 to 70,000 children in the United States per year; this year, the number of hospitalizations has been reduced by 20%. Based on this data, the Center for Disease Control (CDC) estimates that the rotavirus vaccine prevents more than 50,000 doctor visits per year.
Which of the following, if true, casts the most doubt on the estimate prepared by the CDC?
  • a)
    A 2-year-old child is much more susceptible to attacks by rotavirus than a five year old child.
  • b)
    Not all children affected by rotavirus go to the doctor.
  • c)
    Generally, a patient affected by rotavirus has a weaker than normal immune system and thus is more susceptible to other diseases.
  • d)
    The vaccine for Zetavirus, which also affects children of the same age as rotavirus does, prevents no more than 10,000 doctor visits per year.
  • e)
    Rotavirus vaccine is administered to 2 year old children and rotavirus attacks children above the age of four.
Correct answer is option 'E'. Can you explain this answer?

Last year, the United States introduced compulsory vaccination for all...
Explanation:

Importance of the given data:

- The United States introduced compulsory vaccination for all children of a certain age against rotavirus.
- The number of hospitalizations has been reduced by 20%.
- The CDC estimates that the rotavirus vaccine prevents more than 50,000 doctor visits per year.

The question asks for the option that casts the most doubt on the CDC's estimate.

Options analysis:

a) A 2-year-old child is much more susceptible to attacks by rotavirus than a five-year-old child.
This option doesn't provide any information that casts doubt on the CDC's estimate. It is irrelevant.

b) Not all children affected by rotavirus go to the doctor.
This option is partially relevant. It suggests that the actual number of doctor visits prevented by the vaccine may be lower than the CDC's estimate. However, it doesn't necessarily cast doubt on the estimate as a whole.

c) Generally, a patient affected by rotavirus has a weaker than normal immune system and thus is more susceptible to other diseases.
This option is irrelevant. It doesn't provide any information that casts doubt on the CDC's estimate.

d) The vaccine for Zetavirus, which also affects children of the same age as rotavirus does, prevents no more than 10,000 doctor visits per year.
This option is partially relevant. It suggests that the actual number of doctor visits prevented by the rotavirus vaccine may be lower than the CDC's estimate. However, it doesn't necessarily cast doubt on the estimate as a whole.

e) Rotavirus vaccine is administered to 2-year-old children and rotavirus attacks children above the age of four.
This option is the correct answer. It directly contradicts the CDC's estimate that the rotavirus vaccine prevents more than 50,000 doctor visits per year. If the vaccine is only given to 2-year-olds and rotavirus attacks children above the age of four, then the number of doctor visits prevented by the vaccine must be lower than the CDC's estimate.

Conclusion:

Option E is the correct answer because it directly contradicts the CDC's estimate that the rotavirus vaccine prevents more than 50,000 doctor visits per year.

Last year, the United States introduced compulsory vaccination for all...
Because the vaccinations effects have yet to produce a benefit in people who actually get rotavirus. the age of the people vaccinated is 3.

Similar GMAT Doubts

Antibiotics are chemical substances that kill or inhibit the growth of bacteria. The success of antibiotics against disease-causing bacteria is one of modern medicine’s great achievements. However, many bacteria harmful to humans have developed ways to circumvent the effects of antibiotics, and many infectious diseases are now much more difficult to treat than they were just a few decades ago. Antibiotic resistance is an especially difficult problem for hospitals with critically ill patients who are less able to fight off infections without the help of antibiotics.Bacteria can develop antibiotic resistance because they have the ability to adapt quickly to new environmental conditions. Most commonly, bacteria share with each other genetic material called resistance plasmids; these shared plasmids, which contain the genetic code enabling antibiotic resistance, can spread throughout a bacterial population to create a strain of resistant bacteria. Less commonly, a natural mutation that enables antibiotic resistance takes place within the chromosome of the bacteria, and the resulting strain of bacteria can reproduce and become dominant via natural selection. In the absence of human involvement, however, bacteria in the wild rarely develop resistance to antibiotics.In the United States, animals raised on industrial-scale factory farms are routinely administered low levels of antibiotics in their feed not as a cure for ongoing maladies, but primarily as a growth-enhancing agent to produce more meat and also as a prophylactic measure to compensate for overcrowded and unsanitary conditions.Currently, several antibiotics that are used in human medical treatment are administered non-therapeutically to healthy livestock and poultry. Examples include tetracycline, penicillin and erythromycin. This long-term non-therapeutic feeding of antibiotics to animals creates the ideal conditions for the development of antibioticresistant bacteria, as it kills the susceptible bacteria while leaving the resistant strains to reproduce and flourish.Europe is far ahead of the United States in the responsible use of antibiotics: On January 1, 2006, the European Union banned the feeding of all antibiotics to livestock for nontherapeutic purposes. This sweeping policy follows a 1998 ban on the non-therapeutic use of four medically-important antibiotics on animals. The time has come for the United States to follow Europe’s lead.Q.Based on the information in the passage, to which of the following practices would the author most likely be opposed?
