No recall of vaccines containing mercury
Opening
Statement
One
would think that the FDA would have moved aggressively to remove vaccines that
contained mercury from the market immediately.
They did not.
On July 9, 1999, the American Academy of Pediatrics and the United States Public Health Service issued a joint statement recommending the removal of thimerosal from vaccines.[1] On May 31, 2000, the Food and Drug Administration notified vaccine manufacturers that their review of mercury compounds in drugs and foods concluded that reducing or eliminating thimerosal from vaccines is merited.[2] However, there has been no mandatory action. These vaccines are still in use.
The
FDA continues to allow the mercury-containing vaccines to remain on the market.
Today, over eight thousand children in America may be given a toxic dose
of mercury in their vaccines.[3]

in Vaccines—An Interim Report to Clinicians (RE9935)
RISKS OF WITHHOLDING VACCINES
Children who do not receive recommended
immunizations are at increased risk of acquiring serious diseases.23
When immunization acceptance has declined, epidemics of vaccine-preventable
diseases have occurred as evidenced by the measles outbreaks in the United
States in 1989-1991; resurgence of pertussis in Japan, Sweden, and the United
Kingdom in the late 1970s; and the recent diphtheria epidemic in the former
Soviet Union.23,24 Children who acquire diphtheria have a 3% to 23%
chance of dying; 25% of children with pertussis are hospitalized, 22% develop
pneumonia, and 3% have encephalopathy and often suffer permanent sequelae or
death. Hepatitis B kills several thousand Americans every year attributable to
liver cancer and cirrhosis of the liver.25 Hib vaccines have resulted
in the near elimination of meningitis, pneumonia, and sepsis from this organism.
Approximately 5% of children with Hib meningitis die, and 50% of the survivors
have neurologic sequelae, including deafness, impaired vision, and mental
retardation.26 Although these diseases have been reduced to record
low numbers, the organisms that cause these diseases are still present, and
unvaccinated children will be at risk. These serious diseases can be prevented
through immunization. If thimerosal-free
vaccines are not available, physicians and parents must balance the known risks
of serious complications from these diseases against the unknown but much
smaller risks associated with thimerosal in some vaccines. In high-risk
situations, such as infants born to hepatitis B surface antigen (HBsAg)-positive
mothers, the known risks of serious consequences from the preventable infections
far outweigh the risks of adverse consequences from vaccines, even if
thimerosal-free products are not available.
Still using a mercury thermometer? AAP supports elimination of mercury-containing thermometers
In response to the FDA Modernization Act of 1997, the FDA is reviewing the use of mercury in biologic and pharmaceutical products.As a precautionary measure, thimerosal, a mercury-containing preservative is being eliminated from vaccines as quickly as manufacturers can alter their production processes and obtain FDA approval. Currently, none of the vaccines in the recommended childhood immunization schedule contain thimerosal as a preservative.
The recommendation of the Working Group is to state a preference for thimerosal-free DTaP, Hib, and Hep B vaccines as of March 31, 2002, which is when the 2002 Routine Infant Immunization Schedule is scheduled to be announced. The Working Group is asking that this recommendation be issued as a joint statement by ACIP, AAP, AAFP, and PHS, and be approved by these organizations by November 30, 2001.
A study by the CDC was
conducted during the week of September 10-17, 2001 among a sample of healthcare
providers covering 225 sites in 16 states.
The survey asked providers to physically check their inventory of DTaP,
Hib, and Hepatitis B vaccines and to record the number of doses in the
refrigerators, the brand, and the lot numbers. With the assistance of the
vaccine manufacturers, the lot numbers were matched to production records to
determine whether the vaccine contained thimerosal or not. Nearly 66,000 doses
were evaluated.
Among
these doses, 5.5% contained thimerosal.
The breakdown by vaccine type was as follows: among the DTaPs, 9%
contained thimerosal; among the DTaP-Hib combination vaccine, it was 36%; among
the Hibs - 2.7%; among the Hep B-Hib combinations - 0%; and among the pediatric
Hep Bs - 4.6%.
The CDC also conducted a
study of thimerosal vaccines still in depots or warehouses. They sampled two
suppliers, each of which has contracts with 8-12 states. Data collection
occurred during September 10-17, 2001. Just 1% of vaccines contained thimerosal.
There was considerable variation by state, ranging from 0% to 12.3% of vaccines
having thimerosal. Among the overall 1% average, 80% was DTaP, 6% was Hep B, and
14% was DTaP-Hib combination.
