Put you in the shoes of those elders (who may not as luck as you and me who have better education), what will you do if the only authority, i.e., Government tell you that the death rate from Flu is 10 out of a Billion.
Are you going to spent the money on Vaccine?
把你放在那些长者的角度(他们可能没有你我受过更好教育的运气),如果唯一的权威,即政府告诉你流感的死亡率是十亿分之十,你会怎么做?你打算把钱花在疫苗上吗?
