These trials will give a better idea of the number of doses required for a person to be immunized, as well as of the quantity on active principle (antigen) needed in each vaccine dose.
Such action of the antigen pad in the analytical system makes the slope of the dose–response curve steeper but the sensitivity decreases.
抗原衬垫的这种作用在分析系统中使得剂量响应曲线更加陡峭，但也减少了灵敏度。

Reaching even that level of protection required 12 times the dose of antigen delivered by a typical flu shot, and required that the treatment be given in two shots several weeks apart.
