Why has the Washington Department of Health suspended mercury limits for H1N1 vaccine?
State health officials have temporarily suspended limits on the amount of mercury (thimerosal) allowed in H1N1 (swine flu) vaccine given to pregnant women and children under three. The suspension is effective through March 23, 2010, and was implemented to ensure Washington residents at highest risk for H1N1 infection have broad access to the new vaccine. Mercury-free H1N1 vaccine may not always be in stock.
