While proponents argue about the benefits of vaccination for children

While proponents argue about the benefits of vaccination for children, there is hardly any concrete data to back up their claims. However, not only is the efficacy of the vaccines questionable but also are there possible chances of it causing various mental illnesses such as autism. Children who have been vaccinated have a probability of getting the diseases that they have been vaccinated against just slightly lower than national average of all children including the children who have not been vaccinated. So, there is hardly any benefit derived from vaccinations.

Which of the following statements best counters the above argument?


A. A recent study investigating the possible causes of autism found out that the incidence of autism in children who have been vaccinated was slightly higher than children who have not been vaccinated.

B. Since vaccination was made compulsory for children to be eligible for medical aid, the national average for the incidence of such diseases has increased.

C. A recent study concluded that before vaccination, a large majority of children who are now vaccinated possessed immune system much weaker than that of those who are not.

D. The original immune system on birth for the children who have been vaccinated and for the children who have not been vaccinated is, on an average, of equal strength.

E. A number of states have made vaccination compulsory for the children.
