1991-1999: Facts About Vaccines, Lawsuits and Shortages
(continued from previous post)

January 1991: The CDC recommended the universal use of HIB vaccine and hepatitis B vaccine for all infants.

December 1991: The FDA gave Lederle a license for acellular DTaP vaccine for the fourth and fifth booster doses for children 18 months and older and, in 1992, Connaught received a license for acellular DTaP vaccine for booster doses.

January 1993: A unanimous US 4th Circuit Court of Appeals decision affirmed the right of seven adults and children who contracted polio from the oral polio vaccine between 1979 and 1987 to recover damages from the federal government because the FDA permitted vaccine manufactured by Lederle Labs to be released to the public even though the vaccine failed to meet FDA safety standards.

1993: The Vaccines for Children Program was established by Congress, which allocated federal funds to provide CDC recommended vaccinations for all children, without regard for ability to pay. Vaccine tracking systems were created.

1994: Wyeth-Ayerst acquired American Cyanamid and its subsidiary Lederle-Praxis to form Wyeth- Lederle.

1994: The Institute of Medicine published two congressionally mandated reviews of the medical literature, “Adverse Events Associated with Childhood Vaccines,” which confirmed that vaccines can cause chronic brain and immune system dysfunction and death; and “DPT Vaccine and Chronic Nervous System Dysfunction,” which confirmed a reanalysis of the findings of the 1981 landmark British National Childhood Encephalopathy Study (NCES). IOM concluded that “the balance of evidence is consistent with a causal relation between DPT and the forms of chronic nervous system dysfunction in the NCES in those children who experience a serious acute neurological illness within 7 days after receiving DPT vaccine.”

March 1995: The FDA gave Merck a license for live varicella zoster (chicken pox) vaccine.

1995: The FDA gave SmithKline Beecham a license for the first hepatitis A vaccine.

1995: Public health officials at the Department of Health and Human Services, with the assistance of the Department of Justice officials, change the Table of Compensable Events in the VICP to reduce the numbers of children automatically awarded compensation under the Table; from this point on, almost all vaccine victims would be required to meet a higher causation standard for presumption in order to obtain an award in the VICP.

1996: The FDA gave Wyeth-Lederle and Pasteur Merieux licenses for their acellular DTaP vaccines for use in infants two months and older.

July 1996: The CDC recommended all 12-18 month old children receive varicella zoster (chicken pox) vaccine.

1997: The FDA gave a license to a new vaccine manufacturer to enter the US market, North American Vaccine, for DTaP vaccine and gave SmithKline Beecham a license for DTaP.

1998: Andrew Wakefield, M.D. and colleagues in Britain published a study presenting clinical evidence for an association between MMR vaccine, intestinal bowel dysfunction and autism.

1998: The CDC recommended acellular DTaP vaccine for all five doses to replace whole cell DPT.

August 1998: The FDA gave a license to Wyeth- Lederle for the first live rotavirus vaccine (monkey- human hybrid virus) and the CDC recommended it for universal use in all infants in early 1999.

1999: Pasteur Merieux merged with Aventis to become Aventis Pasteur.

May 1999: U.S. House Committee on Criminal Justice, Drug Policy and Human Resources of the Government Reform Committee helds a hearing on hepatitis B vaccine immune and brain dysfunction.

June 1999: The CDC recommended exclusive use of inactivated polio vaccine (IPV) for infants and children, to replace the live oral polio vaccine (OPV) that can cause vaccine strain polio in a vaccinated person or someone who comes into close contact with a recently vaccinated person’s body fluids.

July 1999: The FDA and EPA jointly advised the vaccine manufacturers to remove thimerosal (mercury) preservatives from childhood vaccines as a precautionary measure after a congressionally mandated review of mercury in products revealed cumulative exposures from childhood vaccines that exceeded EPA guidelines.

July 1999: The CDC announced recommendations for use of rotavirus vaccine in infants was suspended due to reports of bowel obstruction in infants. Wyeth- Lederle withdraws the vaccine from the market in the fall.

August 1999: The U.S. House Government Reform Committee, chaired by Congressman Dan Burton, held the first of a several year series of investigative hearings on vaccine safety issues, including vaccines and autism.

August 1999: The FDA gave a license to Merck for thimerosal-free hepatitis B vaccine and thimerosal-free HIB vaccine and gave SmithKlineBeecham a license for a trace thimerosal hepatitis B vaccine in March 2000.
