ATLANTA — Last fall, as swine flu cases mounted and parents desperately sought to protect their kids, the hard-to-get vaccine was handed out in some surprising places: the Royal Caribbean cruise line, the headquarters of drug giant Merck, the Johnson Space Center and a Department of Energy office in Idaho. In some cases, financial institutions and other recipients got doses before some county health departments and doctors’ offices, according to records obtained by The Associated Press through a Freedom of Information Act request. Even though the government spent more than $1.6 billion for the vaccine, no complete record exists of where it went. A partial picture emerges in thousands of pages provided to the AP. To be fair, at least 85 percent of the doses given in the first six weeks went to groups most at risk for flu complications — children and other young people, pregnant women and those with certain health problems, according to an estimate from the Centers for Disease Control and Prevention. Wall Street banks and cruise ship companies accounted for a tiny fraction of the 30,000 or so sites sent vaccine in those desperate early days. "It was a remarkable logistical success,” CDC Director Dr. Thomas Frieden said. "As with many things in public health, the things that work really well, nobody notices.” It’s clear that at many sites, lower-risk people got precious doses in the first two months: →When a U.S. Department of Energy office in Idaho Falls, Idaho, got about 200 doses in October, officials there offered it to higher-risk employees for four hours. When hardly anyone came, any worker who wanted it was vaccinated, a facility spokesman said. →Royal Caribbean got 2,100 doses in October and November, vaccinating low-risk crew members along with staffers who care for children on Florida-based ships. The rationale? Employees aboard ships work with the public and would probably come into contact with people in priority groups. →NASA’s Johnson Space Center in Houston got about 800 doses in October and 1,400 more in November, some of which were sent on to other operations. At Johnson, doses were offered first to employees in priority groups, but NASA also set aside doses for healthy astronauts and their families. Some of the eyebrow-raising shipments to Wall Street firms like Goldman Sachs came to light last year. The New York Stock Exchange got 200 doses by late October. Morgan Stanley in Purchase, N.Y., received 1,000 doses by early November, though the company said it turned over its entire supply to local hospitals when it learned it got shipments before some area hospitals.
