Opinion

MEMORANDUM OPINION

ROSEMARY M. COLLYER, District Judge.

Plaintiffs 1 are military personnel subject to orders to take Anthrax Vaccine Adsorbed (“AVA”), the only vaccine in the U.S. licensed as a prophylactic against anthrax. They brought this suit against the Food and Drug Administration (FDA), the Department of Health and Human Services (HHS), and the Department of Defense (DoD) 2 (collectively “Defendants”), challenging (1) the FDA’s Final Order, see 70 Fed.Reg. 75,180 (Dec. 19, 2005), which determined that AVA is safe and effective and not misbranded, 3 and (2) the DoD’s decision to reinstate mandatory AVA inoculations. Plaintiffs do not contend that *102 AVA is unsafe or misbranded; instead they allege that there is insufficient evidence that AVA is effective to prevent anthrax infection acquired through inhalation. Defendants move to dismiss. Upon reviewing the pleadings and the administrative record and in deference to the FDA’s evaluation of scientific data, Defendants’ motion will be granted.

I. BACKGROUND

Anthrax is a bacterial disease caused by spores of Bacillus anthracis. Anthrax spores can cause infection through three routes: skin contact (cutaneous), ingestion, and inhalation. Without antibiotic treatment, inhalation anthrax has the highest fatality rate — estimated to be 45% to 90%. A.R. at 639 (04 AR, Vol. 3). 4 Cutaneous anthrax has an estimated 20% fatality rate, and gastrointestinal anthrax has an estimated fatality rate of 25% to 60%. Id. at 638-39. In the U.S., there were eighteen cases of inhalations anthrax from 1900 to October 2001, 5 mostly occurring in textile mill workers. Id. at 639. Sixteen of those cases were fatal. Then, from October 4, 2001 to December 5, 2001, there were eleven cases of inhalation anthrax, five of which were fatal. Id. The 2001 cases were all linked to intentional dissemination. Id. Regardless of the route of exposure, anthrax is toxic to the body in the same way. The “virulence components” of anthrax include an anitphagocytic capsule and three proteins: protective antigen, lethal factor, and edema factor. The combination of protective antigen with lethal factor causes the formation of cytotoxic lethal toxin, and the combination of protective antigen with edema factor results in edema toxin. Id.

In 1965, DoD contracted with the Michigan Department of Public Health (“MDPH”) to produce an anthrax vaccine. A.R. 3647-52 (04 AR, Vol. 13). Before the MDPH contact, DoD had contracted with Merck Sharpe & Dohme to produce an anthrax vaccine and prior to that the Army had produced a vaccine (the “original vaccine” or the “DoD vaccine”). In 1966, the Center for Disease Control (“CDC”) filed with the National Institute for Health (“NIH”) a “Notice of Claimed Investiga-tional Exemption” for the anthrax vaccine. Under this investigational new drug application, the CDC began an “open label study” to collect safety data on the MDPH vaccine; the study continued from year to year and the CDC provided annual progress reports to the NIH. The next year, MDPH filed a product license application with the NIH for the vaccine it was producing for DoD. During the licensing process, the MDPH vaccine was named AVA.

The NIH licensed AVA in 1970. 6 The NIH-approved package insert recom *103 mended AVA immunization for individuals with a risk of exposure to anthrax, those who come into contact with animal hides, bonemeal, and fur, especially goat hair. A.R. 3291 (04 AR, Vol. 12). The labeling did not recommend immunization be limited to any particular route of exposure. A.R. 3291-92 (04 AR, Vol. 12). AVA was licensed to be given in a six dose regimen: three inoculations, each two weeks apart, and then three more given at six, twelve, and eighteen month intervals thereafter.

In 1973, the FDA announced a safety and effectiveness review for various vaccines, including AVA, and solicited data and information. 38 Fed.Reg. 5,358 (Feb. 28, 1973). The Panel that conducted the review issued a report in 1980. See A.R. 0001-0600 (04 AR, Vol. 1-2). In 1985, the FDA published the Panel’s report and a proposed order relating to matters in the report. See 50 Fed.Reg. 51,002, (Dec. 13, 2005). As to AVA, the FDA agreed with the Panel’s recommended that AVA be categorized as safe, effective, and not mis-branded. 70 Fed.Reg. at 75,182; see 50 Fed.Reg. at 51,059. 7

To determine whether AVA was effective, the Panel considered: (1) a controlled human field study conducted by Drs. Brachman, Gold, Plotkin, Fekety, Werrin, and Ingraham in the 1950s (the “Brach-man Study”), see A.R. 3732-3745 (04 AR, Vol. 13), and (2) surveillance data collected by the CDC. See 50 Fed.Reg. at 51,058. The Brachman Study involved 1,249 workers in four textile mills that processed raw imported goat hair, a group at risk for anthrax infection. 8 See AR 3732-33 (04 AR, Vol. 13). The workers were divided into three groups: one received the anthrax vaccine; one received a placebo; and one was simply monitored for anthrax infection. Id. at 3732; 50 Fed.Reg. at 51,-058. There were 26 cases of anthrax during the study period, five of which were individuals infected through inhalation. See AR 3734 (04 AR, Vol. 13); id. at 3736 (Table 4). None of the individuals with inhalation anthrax had taken the vaccine, two were in the placebo group, and three were in the observation group. The remaining twenty-one infected workers contracted cutaneous anthrax. Of those, three had taken the vaccine (although two had not been fully inoculated), fifteen were in the placebo group, and three were in the observation group. Id. Based on these facts, the Brachman Study concluded the effectiveness of the vaccine at 92.5%, comparing the vaccine group with the placebo group and combining the inhalation and *104 cutaneous cases. Id. at 3737. The rate of effectiveness did not include data from the group that was simply monitored. Id.; A.R. 1381 at n. 9 (04 AR, Vol. 6).

Although the Panel relied on the Brach-man Study, the Panel found that the study demonstrated effectiveness only against cutaneous anthrax because the inhalation cases “occurred too infrequently to assess the protective effect of [the] vaccine against this form of the disease.” Fed.Reg. at 51,058. “Anthrax vaccine poses no serious special problems other than the fact that its efficacy against inhalation anthrax is not well documented. This question is not amenable to study due to the low incidence and sporadic occurrence of the disease.” Id.
