Control groups regulatory issues

Vaccines are used in either the general population of children or adults or for special groups. Recommendations for vaccine usage are made by the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control. The Committee on Infectious Diseases of the American Academy of Pediatrics (Redbook Committee) also makes recommendations for infants through adolescents, and the American Academy of Family Physicians makes recommendations for adults. An excellent review of vaccine history, development, usage, and related regulatory issues is available (2).

There are two classes of color additives, those that must be certified and those that are exempt from certification. Both are strictly controlled in the United States by regulatory statutes (Food Color Additives Amendments), but an official certificate is required for each commercial batch of color of the first group, while no such certificate is necessary for the second group. For certification the manufacturer must submit a sample of the batch to the Food Drug Administration for chemical analysis. The results of the analysis are compared with the specifications for certified colors published in the Code of Federal Regulations. If the compliance is complete, a certificate is issued for that particular batch of color.
