Can you please describe the arguments against chicken pox vaccination?

Early on -expense: It took 16 yrs +/- to get the chickenpox vaccine through the fda approval process for generalized use. It was available to select populations, but they considered the expense too much to justify broad distribution. When the 50/yr deaths + 10k hospitalizations + 50x increase in invasive strep disease+ work loss by parents was factored in, they finally relented & let it be used.
