Why doesn the FDA recall all thimerosal-containing vaccines intended for use in infants and small children?

Additional studies on the potential for adverse effects of mercury in vaccines are continuing. Results of these studies will be closely monitored. FDA regulations also provide for a voluntary recall of products regulated by the FDA (21 CFR, Part 7). A firm may
