Is Thimerosal a money-saving tactic?Saturday, October 31st, 2009 by:
Thimerosal, a mercury-based preservative, is used to prevent contamination in multi-dose vials of vaccines. Since multi-dose vials are much cheaper than single-dose vials, the seasonal and H1N1 flu vaccines are almost always multi-dose (a few single-dose H1N1 flu vaccinations may be available in November but with up to eight-hour line-ups for vaccinations are administrators really going to deal with requests for single-dose vials?)
Are multi-dose vials really necessary? Would you pay $5 or even $20 a shot for single-dose to make sure the shot was thimerosal-free?
